I thank you for earlier guidance on troubleshooting the heating issue of transistors. I realy appreciaty it.
I would need to ask you for one more advice and would realy like to have your opinion on it.
As I will use the QSXM2 amplifier for my DYNAVECTOR 20XL Cartidge What load resistor and capacitor should be most adequate for my cartridge?
Should I use the following components as per original QSXM2 Scheme and only adjusting the jumpers J1-J4 for MC Cartridge?
R1 (56kÎ©), R2 (1kÎ©) R3 (100 Î©) and
C1(470pF), C2 (10nF)
Should I replace them with with some other values in order to have the QSXM2 preamp "accept" my cartdifge?
I ask this as I have doubts if I should do something like one of the QSXM2 Builders did - Please see the photo available at http://postimage.org/image/2nhs8jqys/
Although on this photo it is clearly the case of the QSXM2 build for MM Cartridge, should Insert some additional capacitors/resistors on the PREAMP Input like it is shown on the photo?
