Hey Robertkoa,

 I have 803s in my MP-1 Classic right now, and TBH, I'm not that thrilled with them there. The classic doesn't have as much low-end response as the original MP-1, and I thought it might help, but it seems to lack the desirable midrange frequencies that I'd like to keep. So far, the Classic sounded it's best with long plate Mullards.

 You might want to go with a shorter plate in the MP-1 to keep the microphonic squeals down to a minimum, or mix it up and use a long plate in V1, and a short plate in V2.

Your ears will tell you what you like and what you don't.

That's pretty cool how you did that layout!

It looks like you photographed your gear and cut and pasted it to a clipboard, then connected all your lines somehow. Nice work!

Quote from: MarshallJMP on Today at 01:42:24 PMThere are 2 ways to measure the current, masure the voltage over the white 0.1 ohm power resistor, ballpark is 40 to 50 mV (milli volts!!!) or take the fuse out and put an ampmeter bewteen the fuse lugs and there you should get between 40-50mA.

This is useful.

I'm also thinking since I'm going to have the amp open and replacing the power transistors, maybe I should also replace caps at the same time?

Pedalboard & Signal chain: It looks complicated, and I admit I had some extra time when I did this, but it's pretty straight forward. See the attached diagram below, here's an explanation;

The Boss MS-3 runs/controls everything. All FX (except a couple pedals) are in there, and all external stuff runs through it somehow...It has 3 loops

Loop 1: Outboard effects (Wah pedal, Octaver & Mojomojo OD)
Loop 2: Amp (via 4 Cable Method)
Loop 3: not used

Notice I have the stomp boxes before the amp, and I have another loop available if I want anything after the amp, but before my stereo delay pedal....

When the signal leaves the MS-3, each output runs into the Echolution 3 L/R. That signal runs out to the amps for each side;
Side A: to the FX RETURN of the main preamp I'm using
Side B: Into the FX RETURN of the amp I'm using as a slave (bypasses the preamp, just uses the power amp this way)

Quote from: rnolan on September 18, 2014, 08:13:20 AMHey El, as SC says my direct experience is with the long plates as the short plates are more recent than when SC and I embarked on our "tube" discovery. He went MP1, I went MP2 and we both loved the result so IMHO you can't go wrong with the long plates MP1 or 2.  For super high gain sounds, the short plates may be better as short plate = less microphonics (I've not had any problems with the long plates, but for 3TM makes sense), I've yet to hear them (SPs) though to compare the 3D and depth, from the patches you've been posting, go with the long plates, you won't be disappointed, they are great tubes  :thumb-up:


I got much more bottom end and clearer gain in the H&K Tubeman  long ago ...smoother singing gain .

I have an MP1 in storage - when  I bring it out ...will the 803s  give more bottom end [ including the cleans ] and smoother gain [ Gilmour Carton EJ etc ]  ?

And also the Sovtek LPS ?
 What do you think ?

 This is the quote from TubeDepot:
" JJ / Tesla ECC803s 'high gain' - Hotter and fatter than the regular JJ, this tube gives more headroom once in the circuit.
Creamy tones and great low end

This was what I noticed when long ago I had a JJ803s  installed in the H&K Tubeman  - more gradual and clearer gain.

But I play Pop /R&B / and Fusion
so gain like Lukather Carlton and
a little more gain but gain doesn't work with complex chords .

The MP1 and Tubeman have been in storage awhile...

I will probably try the JJ803s and the Sovtek LPS  to see if it increases the bottom end .

I like Fender and Marshall cleans  and singing leads / some legato ...I like some of the new Amplified Nations Amps I hear  demos of but  will be recording and don't want the volume in preproduction ..

I like Cab IR's and studio EFX ...
Singing gain with nice harmonic overtones.

The MP1 I have was modded before I bought it noise mods / and lower gain  ...it seems that more bottom end might really push it over the top .

I was hoping someone was using the MP1 more as I did .

If there was a way to get really transparent gain on chords like even cleaner than the EVH Crunch - I might explore that ...but no need go reinvent the wheel .

I may ask Amplified Nation about a preamp that can go right into

Cab IRs for recording .

I think preamps need a  faux phase inverter tube as part of the preamp with a saturation control to add filtering and harmonics to the signal - and sound less sterile .

I noticed long ago that even with cab emulation ...

A broad digital shelving EQ   depending upon preset [ amount of gain etc etc etc ]   - starting  at  9K   and gradually moved lower reaches a point where it does not affect most of the audible harmonics  but gets rid of the harsh hash and odd upper harmonics and improves the tones .
BUT - the modern Rock or especially  Metal leaves these in ...  80's Rock did not because it was all miced and speaker cleaned it up .

Modern IR's do not filter as much as a real mic'ed speaker .

This is why modeling guys are tweaking forever ...lol.

I think two IR's in series might do it .

I am not doing Retro Music at all [ my chords are very very modern ]  but I am not recording harsh guitar tones ...lol.

Not my thing .

Incidentally - Van Halen, Neil Schon, Mick Jones, Lukather, Slash etc. never had harsh tones ...

I like the Amplified Nations demos for tones though including the modded Marshall ones they are not harsh to my ears .

That's what I was hoping the 803s might give me more of with the MP1 when I bring it out.

I want to make sure I have some good+ music before I set ip a whole preproduction rig again ..
frankly.

I think the  Tube Preamps miss the pushed cleans also - Keith Richards , Jimi cleans ...the H&K  does those.

But the Friedman IRX and IRD  sound thin and sterile on cleans and pushed cleans and EJ crunch .

He [ Friedman ] is not going for that and I think a PI tube ( that is padded back to line level - and maybe does not actually invert because there is no rectifier - but Amp guys long ago told me the PI Tube really affects the tone of Amps ...

And NOBODY ever put a faux PI at the end of their tube  preamp  just for harmonics and filtering then padded back down to line level - because the REAL PI tube will be at the Amp stage .

But it is a way to get a little output section harmonics  and the tube has higher headroom and could be pushed different ways .

I am not a builder but if you ARE try it ...

Post here  ..I might buy one.

Hey Richard,

   Yeah, I should have been a bit more specific regarding the networking. You see, I have a room in my basement that I've set up for recording, and that's where the desktop is going to be. I use the laptop when I'm upstairs to get on the internet. I still want to transfer files from the desktop to the laptop though, so the machines need to connect seamlessly. This way, I don't need to be in my basement when I get online to post finished recordings.
