Good evening de EN31do. A.k.a., Des Moines, Iowa, USA area! Very interesting reminiscences! I have quite a few tube manuals, both receiving and industrial, and started in broadcasting in 1952. If mem

Yes, this is the meaning of my posting. In addition, 6L6 and 807 have the same design approach with long internal wires etc. 6146 was designed as an RF amplifier and is much more compact. Regarding p

Hi Jason, I think what Costas was getting at is that the 6L6 was the grand daddy of all beam power tetrodes including the 807, 6146 etc. Yes the 807 has higher voltage and frequency rating than the 6

I'm not sure I agree with this. My Wireless World valve data book from the late 1950s describes the 6L6 as an (audio) output beam tetrode rated for 300V on the anode, 200V on the screen, and deliver

Yes, the 807 is more-or-less an 6L6 with different connections. Costas SV1XV +--+ +--+

Hi Walter, Thanks for the info. Interesting circuit line up. My guess is that its a class-C P.A. The 807 predates the 6146 by about 20 years, so in fact it's a much earlier model than the 6146. -- 73

Re Decca 1615 SG It's a very old tube-type device designed ca. 1960. Tube line-up 6AM5, 12AX7, two 807's (later models 6146's) No risk of blowing up FET's with this one but doubt if the transformer d
