Hey!
I do check out Craig's List NYC sometime to see what out there. Although I rarely see bargain around here but this time I found this....

Silvertone integrated amp. I think it is from late 60's to early 70's sold through Sears I think. Using four EL84, two 7199 and one 12AX7. It said 17.5 watts per channel according to the label underneath.
I went to check it out and to my surprise the seller is a young musician. He hook it up and play it for me. He said he need something cleaner to listen to so he got Adcom pre and amp 535 amp I think and small bookshelf Klipsch and want to get rid of this. Also, he got a turntable too, not a great one, a Gemini. I don't think he is as deep as we are as far as being an audiophile but he know that tube can sound good and admit that some music sound great with this little tube integ-amp. But he can't afford a good modern tube amp now. I did mentioned a few tube amp companies to him that he might want to check out while I was there. He asked for $40 on the post but I gave him my best offer of $30 and he agreed.

Anyway, I bought it home and gave it a good wipe. I checked out closely inside and noticed that PCB is cracked but have the traces been soldered. All pots seems fine not much scratchy and I lube the volume control. There were some hisses and popping sound. So, I checked out those caps. Surprisingly the PSU can caps and all small signal caps of which look like beewax caps seem to measured fine after 40+ years. But there were two caps of which one that I couldn't measurement right. Luckily I have some caps left in my parts box with the same value so I replaced them and now the hisses and pops are gone... yay! haven't try the phono stage yet but the seller said that it doesn't work.
As for the sound. Well, classic tube sound, full tone, smooth mid and high with bloated mid bass sound

All tubes seem to be original except two EL84s. It is very enjoyable. So with that I don't think I will go crazy and change those caps especially those old signal caps to new modern ones.
I haven't measure those tube with my tube tester but after 40+ years I think I going to replace them anyway. The 7199 tubes seem pricey now but I see that there are adapter that allow me to use the less expensive and easier to find 6GH8A. I'm not sure what EL84 I should get? I have some experience with JJ EL84. But never heard others. And what about those Russian Soviet era tube?
So far I think it is a keeper. I always wanted a small tube amp for my TV/2nd system and this seem to works well and sound pretty good... better than I expected for an old amp with small output transformers.

Take care,
Buddy
