Hi FL, the RH universal is a SE amp with a pretty simple circuit. Mine is hardwired and I am so surprised that I don't get any sound from it. I have double , triple, quadruple checked all the connections and don't see any assembly, or wiring errors. Dak
Follow Ups:
Is one leg of the secondary off the OPT grounded? The input's voltage divide hooked up properly? All cathode-tied resistors ok?
Secondary is grounded to a separate ground along with the input jack grounds.
The driver tube B+ is obtained from the mains B+ and dropped via 105k resistor with 50uf of capacitance.
Cathode resistors, 1w mf were checked before installation and are grounded to a 12awg bus bar which is grounded to a power transformer mounting bolt.
It seems like I may have wired the driver tube socket incorrectly but I have checked the arrangement 3 times and do not see anything wrong. regards, Dak
