Hi there,
glad to be here, here’s my first post

I own a 1972 or 73 Freedom P.A. amp. The circuit board is the same as that of the regular Freedom amp but is missing the “Bite” control. I’d like to add that little circuit to my amp. Here’s how that area is looking at the Freedom P.A.:

From pictures I could find in the net I could figure out all the missing parts (some caps and resistors, two transistors, one pot) except for three parts that I don’t even know if they are resistors or capacitors. Two of the parts are only used in the “Bite” circuit, one is in the pre-amp’s Tone section – and the P.A. has a 3.3kΩ resistor there.

I have found photos of two Freedom amp that show the right side of the board, and both have three yellow components with black text or digits (in normal size of a carbon resistor?):

There is a schematic in the web, but it’s quite wrong. It does not have the one resistor both the guitar amp and the pa amp have (the one in the right circle). For the one in the left circle the schematic shows a 2.2kΩ resistor that goes to ground (different in the board) and the one in the middle circle is a 4.7kΩ resistor in the schematic.

All the resistors on the board are common carbon resistors, brown with colored rings. My guess is that the three components in question are three resistors of the same value that has not been in stock in normal version. But have there been yellow resitors with text/digits instead of rings?
Or are they caps? Mallory caps are yellow with black text, but I guess they are bigger. All the (other) bipolar caps on the board are Greenies or ceramic discs.

Does anyone have an idea?

Thanks a lot,
Max
