In the 1952 HB there is a similar rig without the 807, the 6V6 drives a single 813 and the 6Y6 is the clamp tube for the 813.I am getting 665VDC to the 807 plate and 284VDC for the plate for the 6AG7. This chassis was then link coupled to a second chassis with a pair of 813's in push pull. The tube lineup is 6AG7 osc-doubler, 6V6 multiplier, 807 final, 6Y6G clamp tube.The 6L6 (and its big brother the 807) appeared in transmitter article after .Jan 18, 2010 807 integrated amplifier tubes in triode mode, chosen, so that the amp has enough power.The June 1936 issue of QST carried two articles featuring this new tube. ![]() Stalien Push Pull Tube Amplifier using 807. That is why I recommend the 6L6GC type.28 de abr. 83357807Since the screen grid is effectively tied to the plate voltage, and the maximum screen grid voltage rating for the 807 is about 300V, this might cause a problem when the modulator swings down to 100V at the negative modulation peak and the tubes have 440V across them. DIY Audio Home "807" Push-Pull amp (5B/254M tubes driven by the Push-Pull driver board) (Click on the photos for full-size images) This is a pair of monoblock …1 day ago.Over time, the design was refined a bit, but a NOS 807 and a NOS 6l6 are, internally, the same.Mar 9, 2021 You will be happy to know that the 6L6 and 807 are the same tube, but the 807 has been reworked for higher voltage transmitter applications. I want to improve on this design below, as there is no real first stage for this amp, other than the phase splitter itself.The frequency multiplier stage, a Type 807 beam amplifier tube, is tuned to 80, 40, 30, or 20 meters, as needed, by a variable capacitor and coils selected .Even for the new production 807 tubes? I would understand if you "violated" the rating on the 1625. A 75- to 120-Watt CW Transmitter#1 I have a few spare 807 tubes, and thought it would be a good option for me to build a valve amp using them, the only amps ive worked on in the past have used el34 or 6L6 (which shares some similarity to the 807). 181-183 This 15-watt, 80- and 40-meter cw transmitter was intended for the novice constructor. The "Novice Special" Transmitter The Radio Amateur's Handbook, 1971, pp. First Source (s)This crystal controlled transmitter for 80-, 40-, 20-, 15-, and 10-meters uses a 12BY7 and a 1625. Normally replaceable-slightly different: FU-25. 807 tube transmitter Beam Power Tube Power/Output. ![]()
