Further Information

Eric McChanson's 300B amplifier has point to point soldering; a 2-stage single input & driver stage using a 6EM7, then follows the power stage of 300B (SET), with adjustable fixed bias. One 5V4GA rectifier. No negative feedback, 4 sets of inputs, two outputs - 4 & 8 ohm standard.

 

The amp has a deep lush sound that takes you deep into the music. Particularly good on vocals. works wonderfully well, especially if you like lush tonality and timbre of vocals and chamber jazz and classical. 

 

I purchased from a SNA member, he had advised not a lot of hours on the tubes and I have no more than 20.

 

Very easy to adjust the Bias. The test Point is near the power tube. There is no issue if you use Black or Red probes of a digital multimeter; red probe plugs into DC port on multimeter. Set the multimeter to DCV 200mV. With the amp ON, tune the trim pot as needed to get a reading on the meter, for 300B it should be around 50mV to 55mV. 

 

I have included a multimeter. I can consider postage or courier and will investigate options if anyone is interested. I did get a quote from Australia Post and it was $100 to WA. I can also meet at Tweed Heads if you are in sunny Brisbane or if in Sydney and between I am heading to Sydney last week of July and can arrange to meet.
