Garnet P-45 bass amp

[Axtman]

I am looking for a Garnet P-45B bass amp schematic. I think Garnet also relabeled amps with different names. The tube compliment is 12AU7 preamp, 12AX7 phase inverter, pair of 6V6 output tubes and solid state rectifier. Thanks!

This might be it or close to it.

[Axtman]

Thanks! I think that you may be right. I will have to compare it to the actual amp. It is probably close enough that I can work with it.

Is yours actually labelled as Garnet, or is it Piper?

[Axtman]

The amp has no label other than this:

[g1]

That's a Piper model number. Like you said, it's a stencil amp (built by Garnet).
Between the schematic dmeek posted and the one attached (less reverb and trem), you should be able to figure it out.

[Axtman]

Well I ended up sort of using both schematics. There is still no exact match that I can find.

Oddly enough I think this is my first cathode biased amp that I have ever worked on. (Of course most preamp tubes are cathode biased.) I will be very curious to see how it sound when I am done.

Let me know how it goes. I'm looking at the same amp tomorrow. 2X 6V6 's
How does it sound ? Clean muddy like a Traynor maybe? loudish ?
