The Emerald Physics EP100. I will also include a new octet of Electro Harmonix 6V6 output. RF energy from the detector won't be radiated by the antenna because of this. If for whatever reason you "need" to build that amplifier, I would suggest doing away with the triode "strapping" idea through a switch/or not altogether as I have performed many "blind" listening tests with the 6V6 wired Triode and Pentode and could never justify the drop in power output for this particular tube. A 300B “statement” amplifier for Real Serious 300B Fanatics (that’s a technical term!). It won't be quite this high with a 90V B+, but will still give a lot more gain than the triode amplifier. Like a lot of post-war amplifier companies, Magna used war surplus tubes, and would buy large lots of tubes. First, 6V6's expect a plate load of about 8 kOhm vs the 4 kOhm for 6L6's, so the impedance wasn't matched very well.
