Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

Re: Should I power this thing up?(I HAVE NO VARIAC)
Once again, you don't have thermistors in that power amp!Originally posted by TechGeek View Post
Just STV-3s, bias diodes, which will be fine if undisturbed. They're mounted to the heatsink.
If you're confused as to what they are, look at the schematic. The STV-3s have diode symbols, don't they? If you don't have the sch, I''ve attached it.
The only thermistors in this unit are the ones on the prot relay PCB, for temperature compensation, so the trip point is (mostly) the same over varying ambient temperatures."pokemon go... to hell!"
EOL it...

Re: Should I power this thing up?(I HAVE NO VARIAC)
Got a list of caps to replace:
List of caps to replace
Now, is there anything else to replace? And have I gotten all of the caps to replace? I got the caps from the amp, the prot. board, and the tone board. Thank you.Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

Re: Should I power this thing up?(I HAVE NO VARIAC)
my experience with old stuff,
check the power cable - is it still flexible & smooth - not stiff or cracked?
take all the fuses out (one at a time) - are all the clips still tight and springy?Comment

Re: Should I power this thing up?(I HAVE NO VARIAC)
power cable: yup.
fuses: most are soldered in, main fuse holder needs juuuuust a little work.
update: fixed main fuse holderDon't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

Re: Should I power this thing up?(I HAVE NO VARIAC)
does it work? if yes then just change the caps for now.
later you can check switchs & pots for crackle and any backlights in meters etc.Comment

Re: Should I power this thing up?(I HAVE NO VARIAC)
Volume is dirty and one of the switches is dirty. Going to clean it soon. Right now, the signal strength meter is frozen.Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

Re: Should I power this thing up?(I HAVE NO VARIAC)
While I will say prices have gone INSANE with these, the particular unit you have seems to need a tuner alignment very badly. The tuners in these are quite sensitive if they're operating properly.Originally posted by goontron View Post
I'd also recap that voltage regulator board and adjust its output. The tuner won't work for crap if it's out of whack.Comment
