^ really worth it to invest in. a real desoldering station would make life so much easier. nice tool to have around. if i had to do this all over i would have bought that first. wick and flux are tedious. it works but it's slow slow going

I have a ZX450 which has issues with the gain varying on its own in one channel. After switching on, after a few minutes the gain increases suddenly. It might be a pot issue but I don't really know. ZX amps could be better if the crossovers could be removed entirely. The crossovers were state of th...

thought i would make this for an archive post. hopefully it saves someone else a bunch of time if they are restoring one of the zx amplifiers what are you looking at? zx450v2 input capacitors are nichicon pwm series 8200uf 16v part number UPW1C822MHD rail caps are CDE or cornell 3300uf 50v part numb...

would certainly think so. the ms2250 was an absolute beast. a headlight dimming monster masterpiece. that was a low production amp to begin with. especially if you had the fan shroud

seems like select old school pieces are pulling a premium. some i totally understand. some i kind of wonder about. hifonics series 6, 7, 8 are selling for a premium now which i really don't quite get. i have nothing against zed at all but those amps, while decently made, were not on par with zapco o...

i haven't really been keeping up with car audio over the past 10-15 years. that said i have noticed pricing on the M amps is over what it was back around y2k. considerably so actually {not inflation adjusted} when these released they were marketed as a lower cost alternative to the MS amplifiers. no...

do you actually re rivet them? may have to keep you around for future tasks i realize i'm a noob on this forum but have been into PG since the ms275 first released and actually gave zapco's z150 a real competitor for best early 90s 2ch 75w the only guy from the old days i have chatted with somewhat ...

thank you for the reply. i did end up changing the smaller caps along with the main input/rail caps on the zx450 with no issue. just had to be really careful with the heat and braid when desoldering i did however have a minor issue with a xenon 100.2 that i was bumping up the input rail caps on. on ...

just going to bump this one since the topic already had recent traction have there been any issues with the smaller 100uf and under nichicon caps found in the Zx / Zpa amps? have a zx450 here and swapped out the leaking psu caps for 8200uf nichicon pwm and the rail caps to cornell 3300uf snap ins. s...
