Hi group,
I ran into this web site with a very detailed account of the 6L6 by Eric Barbour. I thought the group would like this. After all how many AM modulators use the 6L6 / 5881 tubes? I can think of the Elmac AF67/8 and Ranger as two examples. The 807 / 1625 / 6BG6 are repackaged 6L6's so with these tubes the AM modulator list gets huge. Eric also talks about the 7027 and 7581 as an offshoot of the 6L6. He also states that the 6L6 is the first tube to use the Octal socket. Is that correct? Now I understand more about why my QRO'd Central electronics 20a's have lower than expected efficiency using power pentodes (7591 and EL-34) as the RF output amplifier as opposed to beam power tubes... Enjoy!
