Postby eldub » Tue Jan 22, 2013 5:11 pm

Hey ,kids.....

I just purchased an sca-35 and would appreciate help in finding the materials needed to modify the unit with DG's efb bias circuit.

Thanks in advance.

Thanks, battradio.

I just went to the mouser site and asked an online rep if they carried an enhanced fixed bias regulator for a dynaco sca-35 amp and the guy said he needed more information. Can anyone point this noob in the right direction?

Thanks.

I just found this information....

Mouser # 511-LM337SP
Linear Regulators - Standard 1.2-37V Adj Negative

Mouser # 71-CPF15R0000BEE14
Metal Film Resistors - Through Hole 1watt 5ohms 0.1%

Mouser # 652-3296Y-1-502LF
Trimmer Resistors - Multi Turn 3/8 5Kohms Sealed Vertical Adjust

Anything else needed than that which is mentioned above?

eldub -- A BOM, instructions and a bare EFB power supply board should be available sometime next month on the Tronola website.
