A few (fairly) easy Blues Jr. Mods....

[Commodore 64***]

Mine's rated at 500v, so it's a little bigger than the existing, but your description is EXACTLY what I needed to know. I won't even have to remove the PCB then, to do this mod. Sweet

Also, would either of these trim pot work for the bias mod?



Pot - 3K Linear, Trim, 0.60" OVERALL Body DIA, PC Mount
3K, CTS.


Pot, 1K Linear, TRIM, 0.60" Overall Body Diameter, PC Mount
1K, CTS.


I ordered a couple of each with my last order, figuring they might be useful someday.
