I can help you with this if you want to try this. A 300B would sound great! The 6b4g is an octal 2A3 so lots of great midrange. I would try using resistors from Mills. You can buy these on line at parts express.BUT I would try to find a device like my Carver coupler. I know car audio stores have high to low adapters for car radios to turn the power out channels in to low level RCA signal levels for amps and being most SET amps are less than 25 watts this shouldnt be a problem. The Carver coupler I am using is the same thing just made specifically for home audio. That should work. If you still have issues I will get exact specs for your amp and help you build one just for it. Let me know if I can help further. Jay
SET pre-amplification?
I recently took an old 6b4g SET amp and converted it into a preamp. WOW!...I never have been so close! I get 90% of that SET sound but with the benefit of a higher power tube or SS amp at the end of the chain. I am still playing with this and I have found the only draw back is hum. It is 60 Htz which is normal heater hum so possibly the filaments should be DC heated not AC. Just sharing so you to can experiment. Good luck!
