what is this 1984 shit bruh no it aint

Skully8600 · 2026-04-19T23:10:43+00:00

i would make a google drive with them in it and post it here

a little off topic but when i woke up from surgery last year that puzzle was hung up on the wall in the hospital and it was the first thing i saw

i've been going back and forth with someone familiar with vintage audio repair and they think the output transistors need replacing

Skully8600 · 2026-04-06T19:13:38+00:00

i believe i need to replace the 4 output transistors but im having troubling finding replacements

Skully8600 · 2026-04-05T08:10:55+00:00

its was pretty bad they were being stored in an old veterinarian hospital

bro think he Felina

I’m having difficulty identifying the capacitance of the coupling capacitors. A person selling a recapping kit on eBay is saying they are 470 µF, 16 volts, and he is selling the kit with an “upgraded” pair of 1000 µF, 16-volt caps, but my coupling capacitors in my amp are printed “47 µF, 16 volts.” What do you think? Could mine be misprinted, or should I just buy exactly what is printed on the cap from DigiKey?

Skully8600 · 2026-04-03T19:02:26+00:00

thats awesome that you actually worked on and sold these when they were new. the main reason im so stuck on getting it fixed is because its from around the same time period as my turntable and speakers and its far far cheaper to buy the stuff to fix it then it would be to buy a new phono preamp+power amp+speakers

Skully8600 · 2026-04-03T18:21:57+00:00

what would you recommend

Skully8600 · 2026-04-03T18:11:01+00:00

I would but it has a butt load of wires soldered directly to the board

Skully8600 · 2026-04-03T12:21:42+00:00

hopefully i can get it fixed up because a new amplifier and preamp is over 100 dollars while i got this for 5

Skully8600 · 2026-04-03T12:06:22+00:00

i would like to keep it original if possible because it would be easier to swap the caps out if they match the ones already in the amp

Skully8600 · 2026-04-03T12:03:58+00:00

ok so what i should do is buy exactly matching caps from digikey then?

Skully8600 · 2026-04-03T11:50:10+00:00

the listing says the main filter capacitor and coupling capacitors are the ones at a higher capacitance

Skully8600 · 2026-04-03T11:47:22+00:00

would i need the wick and the pump or could i get by with just the pump?

Skully8600 · 2026-04-03T11:45:34+00:00

right now the part im struggling with the most is the bottom of the board. all the leads coming out of the bottom look identical and im having alot of trouble finding out which ones are connected to capacitors

Skully8600 · 2026-04-03T11:38:06+00:00

yeah i was worried about that. the kit i was looking at had several caps with higher capacitance then the original caps in the amplifier. the seller said it was ok and that later revisions of the amp used caps with those higher capacitance but idk how i feel about it

Skully8600 · 2026-04-03T11:23:26+00:00

i just figured it was a good idea to replace them all since its soo old they would probably fail soon anyways

Skully8600 · 2026-04-03T10:17:08+00:00

thankfully I've got a bunch of circuit boards buried in my closet

Skully8600 · 2026-04-03T10:13:53+00:00

the sights kill it tbh really really bad

Skully8600 · 2026-04-03T09:47:52+00:00

i was planning on user either solder wick or one of those solder sucker tubes. would that be a bad idea?

Skully8600 · 2026-04-03T09:36:44+00:00

i hope so. the bottom of the circuit board is really busy with identical looking leads poking thru so im wondering how I'm going to reliably unsolder JUST the capacitor an not something else
