Does anyone have a copy of the SAMs for a magnavox 142 bc amp?
« on: October 04, 2014, 09:07:16 PM »
Hi guys I'm getting ready to recap a magnavox 142 bc amp, does anyone have a copy of the SAMs they can scan and email me or upload to the download section here. I'm sure others would benefit from having that added to the download section,it's a pretty common amp.
Thanks :)

Did you find the SAMs  for your 142?  If not, I have one that I could try to upload. Curt

Hi Curtis, yes please do I havnt been able to find it. Like Pat had said others may need it to, thanks so much. The issue I'm having is, on some amps it tells the voltage and my. The one I have are the black caps with color bands, the amp not has 3 caps in it. Someone said the two in question are .1mf 630 volts. I have seen the same amp before with the caps marked that but mine is the ones with the color bands and I can't read them. I assume they are the same but needed to confirm :) I don't need to ruin the amp

I'll try and get that later this evening.  Mine had the same caps and I'm not sure but I think they were 0.1 mf 600V.  Regards Curt

Ok
Well if anyone has a copy the a
Can scan in of all I realy need to know is what them two black banded caps are
I'm assuming they are the same as the ones marked in other amps. Why magnavox did that is a mystery to me.
If someone can confirm that's what those two are that's all I need. Maybe someone has a pic of the underside of that amp before a recap showing what that are? I was told .1 mfd 630 volts but I need to know for sure :)

I found this at Audio Karma under the tread of " Can someone PM me the SAMs for a 1957 Magnavox 142 BC power amp"  there is also the mention of the 0.1 uf  black beauty coupling caps in the thead.  Good luck in your restoration. The two I had sounded great. Ill check to see if I have a old picture of the under side. Also it looks like the C5 caps are the ones in question.

I found the pictures of the under side.  Note the yellow 104k or 0.1uf caps.

Yes o.1 mfd or uf ,same thing. And  630 volts will be fine. If I were to do it again, I think I'd try a pair of the Russia k40Y9 rated for 600 volts. for the 0.1 mf coupling caps. I've liked them in other amps.
