Silvertone 1464 hiss?

[Axtman]

Is anyone familiar with Silvertone 1464 solid state 100 wall guitar amp heads? Do they have a noticeable hiss with no guitar plugged in? Thanks.

Preamp or power amp?

I couldn't actually answer the question. Haven't worked on one of these for a long time. Is the hiss still there with all controls all the way down?

Thanks for the schematic. I did find it previously but only in individual pages. Now if I could only find a Slivertone numbers to actual transistor model numbers.

The hiss is through the speaker with the controls all the way down. I am wondering if it is not the germanium output transistors.
