Hi dante

Power supply scheme for MP1 is not available as it is directing to the JacksMP1 scheme.
Can you fix this? I'm trying to replace the transformer, so I wonder the power supply scheme will fit my needs,

MM of thxs for keeping ADA rock the world!
Title: Re: The Vault = Schematics and Mods
Post by: John Mac on April 22, 2014, 11:40:23 PM
Having looked at the schematics of the MP1, MB1 and more closely at the MP2 I recommend that any ADA product user buys the best power filter / surge suppressor they can to avoid unwanted power surges doing nasty things. This needs to feed a powerboard with the connections to the rest of your gear. I have some backyard suggestions if you are located in areas subject to a lot of lightning but the best idea is to unplug everything from the wall when you are not using it.

Not wanting to be the bearer of less than positive news but unfortunately a few of the chips that are in the MP2s do not appear to be manufactured by the original manufacturer and this may make future repairs significantly time consuming whilst alternative replacements are sought. There may be alternatives (like the power mosfet debacle by Toshiba) where chinese manufacturers launched alternatives however some of the chips are quite specialised. Perhaps a second unit may be an alternative.

If anyone in the service industry has details of suitable replacements it might be worthwhile posting these in this section.

If I have motivation in the coming months I may have a look more closely and have a search of alternatives if there are no helpful replies.

Cheers all.

Hey John, this post (http://adadepot.com/index.php?topic=311.15) if you haven't seen it is quite interesting, replacing all the opp amps.

I've found my MP2 and to some extent my old MP1 are not fond of generators, they go space monkeys in the middle of a solo etc and the only fix is boot them.  I now use an UPS (1 kva uniteruptable power supply) which isolates me somewhat (go with a de-coupled UPS).  I went the ups way because they are cheaper (albeit heavier) than a decent power conditioner, down side is the battery goes off over time, upside, they are probably as good if not better than most power conditioners and heaps cheaper (I paid ~$160 AUD) (shit loads around as everyone has to have one now for their home office....)
Title: Re: The Vault = Schematics and Mods
Post by: MarshallJMP on April 23, 2014, 01:52:49 PM
I have a good supply of all the obsolete chips in the mp-2,so no worries :lol:
Title: Re: The Vault = Schematics and Mods
Post by: John Mac on April 26, 2014, 02:40:54 AM
Good work MJ

I also discovered some of the aircraft parts suppliers still have stock of the electronically controlled resistors as well


As far as UPS goes, i work for a large health organisation that has about 1000 sites and a coverage area of 1/3 continental united states and the one thing we learned quickly is that most smaller ups need a surge suppressor on the input. We use 3KvA filters that are a bit large for this application but unless you are using a $500.00 1KvA ups it is just as susceptible to risk
(On the neat side is once we started putting filters and ups in surge susceptible areas that we uncovered all sorts of other hardware issues hidden by crapy power. )

Sorry didn't see your post...  For now most of the 3TM mod stuff is in the MP1 section IIRC, but there's bits all around depending on what's being chatted about (lots of posts though).  The schematics mods section is developing, we have what we have so far, and happy to add more, and happy to add a 3TM section (although MJMP would be better suited to do that).

What does the acronym HDRM on the preamp schematic mean?
I have searched the net but cannot find it.

Looks like it either stands for High Data Rate Multiplexer (a digital data splitter) or Hold Down and Release Mechanism. My guess is it is the latter and it is referring to a connection to the front panel membrane.

HDRMs are the signal monitor points that go the clip LEDs on the front panel. Probably short for Headroom.   :thumb-up:

Hi folks, where can I find the schematic diagram for the Mp1 V1 and V2 main board. I have looked at the PCB layouts that are here but I would like to have the actual MP1 schematic as I would like to study it to see whats connected to what. It would be really nice to see it if that would be possible.

I'm sorry folks, but is the schematic here somewhere on the forum that I have mistakenly overlooked and not looked hard enough for or maybe I'm getting old   :)

Thanks in advance folks.

Hey Rusty, the MP1 schematics are here (http://adadepot.com/index.php?topic=148.45). What we don't have is a nice diagram of the signal flow through the MP1 like on page 3 of the MP2 manual which is very useful from a gain structure patching sense (better/more useful for what connects to what). I did ask MJMP if he'd do one for us (as he knows the MP1 backwards/forwards and sideways LoL) quite a while ago. Hopefully this post my jog him to do it ? (please  :bow: ).

Ahhh,,, I think I need new glasses. Thats what I was looking to see. I will take a good look at both the MP1 & MP2 schematics. If MJMP could do something like that I think it would be an awsome schematic to have and the man would deserve a gold medal and the Nobel peace prize together.

I do know that it would be quite an undertaking to start from scratch laying out the schematic on a electronic software package, plus given that the MP1 has the track on both sides of the board it would make it double the chore.
I use a couple of electronic design software packages for my own little projects. I used LTspice for several simulation models and I think that it's an excellent powerful little piece of software thats free to download. Another package that I use from time to time is National Instruments Multisim and Ultiboard. I was educated on that one and I use it seldomly to test out my little circuits.

I could 'possibly' give MJMP a hand to lay out the schematic depending on which software package he uses, some of the spice variants are compatible with one another I think. But if he knows that board inside/outside/upside down then he's light years ahead.

Thanks for that rnolan, much, much appreciated.

I was thinking something along the line that rnolan suggested and was thinking to make a more compact consice signal flow diagram of the audio signal path only leaving out the digital control blocks. Your right though, its all there after having a proper look through the scematic that you kindly posted up.
I probably got too far ahead of myself with that post as I didn't get a decent look at that scematic.  ::)

The schematic is quite good,try to compare that with the MB-1 schematic,now that's a mess.

Maybe have a look at page 2 of the MP2 User Manual "Signal Flow" diagram. This is what I was suggesting would be useful for MP1/Classic/3TM etc. This diagram is very useful for patching, gain structure etc, it's not a "under the hood" diagram as such, but desalinates where you can come and go. E.g. when I thought to use the MP2 cab sims with an MP1, you can clearly see that by coming in the MP2 FX returns (ie MP1 A/B out > MP2 FX rtns A/B), and after that you pick up (in the MP2, If you wanted ?) Tremolo, Stereo Volume CC, Room eq (this is very useful BTW), Output level and then cab sims (I recommend the 2 x 12 setting)). Reading this page helped/set me to test this scenario. Which worked a treat  :thumb-up:
@MJMP, so not really a schematic, just a signal flow diagram of MP1/classic/3TM? (not sure 3TM would differ from MP1 in this context) and MB1 would be really useful.

DONE. You'll notice a much longer list of schematics for the MP-2 in the Vault (http://adadepot.com/index.php?topic=148.0) now

I also found some schematics for the MXC controller, I'll get those in here too

I was looking through some old stuff and found some pics with notes about MOD3.1 

Remember that the MOD3 needs to be done first before applying this revision.

WOW found everything I need right here!!

 So a quick question those in the know - to do "just" the mid scoop mod on the MOD3.666 basically I could just change out R151 with the new value couldn't I?

I'm loving the fact that it says you could go from -12 to around -30!!  :headbanger:
I'd be happy with around -14 or -16  ;D

Yeah for sure  ;D I just need a little less than what is available to drop now.
 I'm gpnna do this mod, just need to see where exactly this set of components are on my board for the mid EQ section.  :D

Where is the battery clip mod?
Title: Re: The Vault = Schematics and Mods
Post by: rnolan on July 05, 2018, 02:16:20 AM
This is for the MP1, the MP2 battery is vertical.  Also this will erase all patches, so you'll have to reload the factory presets into RAM (from the EPROM) and reprogram any other patches.
