No Worries Will, it's been added to the list of Mods (for now)

I can see (by MJMP's donations) I'm going to be splitting things up a but as we continue to grow the vault. Which is cool  :thumb-up:

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!

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....)

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. )
