PM me if you need options on BB replacements. I will share what I have found to work, and since there are ONLY two op-amps used by PG its really not a big deal, just don't get them mixed up or you can cause circuit instability, and a nice fuzz will appear on all your audio that pass's thru the amp.....

:shock: :shock: There is 21 BA4560 op amps inside of a ZX450v.2 Ask Dedlyjedly both of his Ti-500'4's have a complete BB compliment in them. :wink: Not a single JRC 45XX was left inside them. I have A B'ed exact same amps before and after to my fellow tech's and blind tested and "every time&qu...

I've been doing the PG non-warranty repairs at PG for the past 6 weeks. The flat rates haven't changed. Hi Roland, I have sent you a PM......C I have never in the past doubted PG's repairs or policies. In fact I use them to set my own rates by in the past. To my business knowledge PG has had very f...

I hav...

Does anybody know who can fix these? I need a new power supply. As long as the board is not burned up any so-so tech can rebuild the power supply. Its just mosfets , drivers, and gate resistors normally. Not really a big deal unless you get a ding-dong that can't follow the simple rule of replace t...

Any Pics yet ? especially of the inside ??? The 400.1 sounds like a winner in modest clothing...Please post more info soon, and any internal pic possible, My interest is peaked by the TO-3 outputs. This should do well against the OS Linear Power folks out there. LP was a text book Motorola design am...

I have seen this and it is explainable: The original first runs of the M series boards were Gold plated just like MS/MPS series amps. Standard production back then. Now Why Gold plating in the first place, Well Gold is INERT, it will not corrode, Copper corrodes. PG Gold plated to prevent corrosion...

Correct me if I'm wrong but this amp is ZED in origin. I have its little brother sitting at the foot of my bed currently collecting dust... YUP I got a USA2150 at my feet...and they were made by ZED here in So Cal..


PS ZED I don't think I need to say more to anyone here....

Good nite...

OK, this is perfect, Thank you. Your outputs are IRF-640 and IRF-9640 This amp uses both P and N junction outputs in groups of three.( Each group of three is arraigned to act like one big fet) In the group that reads bad you probably have a single shorted fet, and it will cause all three to read sho...

I hear its one Hell of a way to go May your wish be granted

You better watch out ydhap, you might get what your asking for and more They can ride a lot longer then us Cowboys can, if you catch my drift.....

Your a strong fellow Andy, a real strong fellow

the output with none of the 8 power mosfets in rings out to 990kohms on the speaker outputs Go the mosfets in the amp section and read the ohms between each pair of the three legs on each Fet. I.e. read from center lead to either leg on left anf then right... You should get no low reading any where...

I know Thats what got me worse then the shirt was that smile Neeheehee Brupppphh...
