Hi,

http://bmamps.com/Schematics/Rivera/Clubster%2025-45.pdf

This is a Rivera Clubster 25 guitar amp.

From the input there is R102 to C101 to Q101 which is marked as 1FN6448 on the schematic. There is only a Rivera part numbers on the transistor. I assume it is a transistor. Round metal top with three legs.

What is Q101? Data Sheet?

Thanks,

Billy

One of the issues is that I have no signal on the grids of V1 and I assume this component may be the cause.

It is a junction FET. Can you read the part number on the device? Could it be 1FN6449 ?

Q104 appears to be a 1FN6449 - if this is the correct part number it is a Jfet made by InterFET. They claim it is equivalent of a 2N6449.

No part number other than (Rivera 104-010-0450) that is marked on the device.

I assumed a FET of some sort. I think it is possible that it is a 6449. The schematic is a PITB to read!!!!

Also...thanks for the help

Cheers,

Billy
