Title: Tube PCBs
Post by: AcdNrg on April 01, 2025, 11:37:55 AM

Are the tube PCBs on True Grit and MU524 the same?
 
And is this the right socket:

Noval S9CPC-1
18mm diameter
UPC: 4251594908081

I messed up one of the two MU524 kits and need to replace the whole rube assembly. Since the TrueGrit has spare tube PCBs, I wonder if I can use these.

The tube PCB's are the same except for the test pins added on the True Grit.
The tube socket is this one:
