I have in the past worried about the different input voltage and matching of the higher output of hi end eclipse units. 8v output into a m44 would get maxed out real quick and then you have the zx which can take more. Active option I guess would give you control of matching those up better but the s...

Do you have to change any resistor value's when you upgrade the FET's

Have you moved any of these my M 44 top is pretty rough .

Thanks did the normal thru hole repairs and all is good got the amp up and running all new caps. It's a Xtant 1000.1 D super clean. Had it in my old 94 bmw 525 touring with 2 old school eclipse 8810's it was one of the tightest cleanest sub systems I have ever heard.

Ok a while back I repaired my zapco 1000.4 and the silver solder was a PITA . Now I am doing my Xtant 1000.1 that a cap started to pop on and it alsp has silver solder . I have a Hiyua 862BD and it has been pretty good for a cheaper station had to solder in a new tip after a year or so. I pulled one...

Old Thread but I repaired my reference 1000.4 and put some better caps in while doing the other repair work good to have it back in action. I do still have the ZPAs and need to do something with them sell them or trade out for some work . I am too deep in repairing vintage saxophones to deal with th...

Had it exchanged and new serial number for around 240.00 they said they repaired it but it was a new one.

Well this is an old thread but I have a collection of amps with problems caps being 1. Been running zapco amps for years now mostly the reference amps made in usa and havent had a cap issue was that later built reference built overseas? The good ones had gold plated terminals and were black with the...

Anyone know about recalls on these I have one that went out power light goes red green flashing back and forth and its not a low battery power or ground issue. I read that they had problems with them. Picked up used with a 600.4. JL did recall some 750.1 not sure about the 1200. I know what your thi...

Starting to get some bulging in the top of the PS caps they are to 50v 2200uf limited space on these 22mm x 28mm any part numbers would save me hours looking through digikey site

Jimmie

Anyone sporting one of these about to get one for the wifes car I have a eclipse CD 8051 in my e34 touring and it sounds outanding had to clean the volume pod but since then its been flawless with a zapco 360.4 and a ZX500 on my sub.

I have been roasting my own beans purchased from Burman Coffee and they sell some great beans My favorite is the haitian blue mountain which is jamacian blue mountain plants grown in haiti its a fraction of the cost of JBM at 9 to 10 bucks a pound and is really special. I drink sumatra mandheiling t...

I think the later TI amps will take higher input voltage 5 or 6 volts.

I forgot to add they only do 4ohms bridged but really shine on a sub.

Jimmie

The reference line replaced the earlier AG amps but are the same just different color been running a couple 350s for few years on subs and diamond audio hex comps and its the best sounding setup I have had to date. Also have a reference 1000.4 its a beast. I still love my old school PG stuff but its...

Thanks Im on it.

Jimmie

The holes are really close together might not be enough room get both nuts on I guess I could enlongate the holes if I had too.

Jimmie

I recapped this amp a few years back and it was a beast of a little amp but one channel quit and its the rca inputs I searched some and went to digikey and spent way too much time searching their. Looking for a part # and where to get.

Thanks
Jimmie

I would check the caps they may need replacment its rated at 100 watts RMS x2 @ 8 ohlms. I have a citation 16 running mids and tweets on some kappa 8s and a mackie 1400 on the woffers and a citation 17 preamp that I recapped and it sounds pretty good love the old HK gear. Nice score good luck I read...

Just did 2 zpa 0.5 amps

Digikey
493-1544-nd 16v 6800uf
P6668-nd 35v 15000uf
P6692-nd 50v 12000uf

On the 0.5 you have enough room to go 45mm height wise. Cant tell you how many hours I spent on the digikey sight looking these up. Hope it all goes well.

Jimmie

For future refs on caps for zpa 05 I picked the P6692-nd 120000uf 50v they are 35mm w 45mm h p6668-nd 150000uf 35v 30mm x 45mm 493-1544-nd 6800uf x 7.5mm x 40mm The 35v caps need to be no larger than 30mm width not enough room in the middle. Seems to be room to go up to 45mm in height on the zpa. Im...

I replaced all the caps on a few boards in the preamp and it sounds great. Its been a while since I was on here and most dont give me the time of day but I know how it is its all good.

Jimmie

I opened the amp back up and it has the 35v 8200uf black caps in it. I thought I have seen some with the blue caps and thought they were 50v 10000uf. I found a 35v 18000uf that will fit 35mm x 35mm any reason I should up the voltage on these caps

Jimmie

I need to find some main rail caps for a m44 the big ones. I have looked on the digikey site and if Im not mistaken the height is the issue 35mm I found some that are 40mm but not 35. I dont have the case open right now but was thinking they were 10000 uf 50v.

Jimmie

This was a long time back but trust me and dont buy the eclipse stuff Im going with DLS gothia 6.3 and bridge my m44 on them. Anybody have some feedback on the gothia speakers?
