Hello all, just wanted to ask if anyone knows where I may be able to locate a schematic for the Sears Silvertone model 1465, I have looked everywhere. Google, Bing, Yahoo, you name it. I saw that there is a Silvertone section here on the site in the schem section, but this model number is not listed on the site that the link takes you to. If anyone has anything they can contribute, that would be amazing. Thanks so much.

Hello all, I'm new to the forum, but I'm glad I found it because this seems like a place where I can find some real answers. I am the proud owner of a Sears Silvertone Solid State 150 (Model 1465). I just recently opened up the head to clean it (I don't think it had been cleaned since it was manufactured). This amp was a gift to me from my dad when I was about 17 and I have kept it ever since. It sat in storage for some time (about a year) where it wasn't used. I plugged it in and it sounded as good as ever. Then I took the head out of its old casing and blew out a LOT of dust that has been building since I'd guess around 1968, haha.

Anyway, this amp used to be notoriously loud, to the point where there was no way I could turn the volume knob above 4. After blowing it out I took some q-tips and isopropyl alcohol and cleaned off some of the gunk that had built up on the back of the volume pots. I made sure that the q-tips were not dripping but only damp, and what came off of the back was an unbelievable sight. There was a LOT of filth that had built up on the back where you could see the rod come out of the back of the pot, there was literally stuff falling off of them just from turning the knobs on the front and making that rod on the rear of the pot spin. (sorry if I'm using incorrect terminology, I'm totally green here).

After cleaning them, I replaced the power cable because the old one had a very large area of wire exposed. I installed an 18AWG SVT cable with a ground (the old wire did not have a ground, it was just an old 2 prong plug), attaching the black wire to an existing black wire where the old cable had been soldered in, and the white end attached to the 5A fuse housing that holds the 5A cylindrical fuse. I then attached the ground wire to the metal chassis that the circuit board is mounted to (the board is held away from the metal by plastic spacers.) Then I stalled a 1/2" bushing in the hole to protect the cable.

Well, after putting everything back together and putting in a brand new fuse, I turned it on, with no unexpected problems. No pops or crazy noises, but now when I turn the volume up, it responds up until about the 1 -2 mark on the knob, but then the volume stops climbing, no matter how far I turn the knob. Even at level 10, it sounds only as loud as about 2. It is not distorted or making pops or cracks, and the hiss doesn't sound any different than it ever has with this amp, mainly just normal sounding line noise I hear with any amp. This amp has two inputs per channel, and two channels. I tried all of the inputs and both channels, and I found no difference per input, and also the second channel is doing the exact same thing.

So there you have it, just trying to figure out where the monster that used to live in this thing went... I'd like it to come back soon. Solutions or suggestions welcome. Thanks so much for reading.
