ben. Posted August 2, 2003 Share Posted August 2, 2003 I've got a stash of NOS RCA 6BG6G tubes, and am knocking around some ideas for using them. 1- Single-ended Pentode design for 2-ch playback system. 2- P-P integrated 2-ch 3- Music instrument amp guitar and/or bass Anyone have any ideas, warnings. etc. Any volunteers to build em?

Deang Posted August 2, 2003 Share Posted August 2, 2003 Turkey -- it's only a "Homebrew" amp if you build it. Quote Link to comment Share on other sites More sharing options...

Deang Posted August 2, 2003 Share Posted August 2, 2003 Hell ya I'm chicken -- Could always do a nice kit, but then you couldn't use those tubes. http://hollowstate.netfirms.com/ http://www.audioelectronicsupply.com I could probably handle a kit.

Marvel Posted August 2, 2003 Share Posted August 2, 2003 If you look on the Triode Electronics tube data page at the 807 tube, they indicate that other than the basing (I think they mean biasing), the curves are the same for the 6BG6-G tube. They have links to a 75 watt AB2 amp using the 6L6 or 807. This could point you in the right direction. 6SN7 phase splitter/driver.

mike stehr Posted August 2, 2003 Share Posted August 2, 2003 Some of those horizontal tubes are pretty linear from what I understand. The GE data for 6BG6G does indicate amp factor of 8.0 in triode mode. I'm sure one could find a OPT that would match up, same with the power transformer. I might be wrong Marvel, but I think they mean pinout when they say "basing". Be aware of the high anode voltage that will be on top anode cap, which would be above chassis. SE with a bit of feedback that possibly could be switched out. I would like to try this with a KT-88, hell, this 6BG6G tube is dirt cheap however.

Assuming this is correct, Gordon Rankin had a really nice schematics for a single ended 807 in Sound Practices vol 1 no.2. I think (not sure though) the PDF version of this article is available through the Wavelenght Audio web site. It's a really nice and good sounding amp. One of my friend built it and I must say I was quite impressed. And you must know that I have a STRONG bias against single ended amps with anything else than a DHT. You could also build an "original" Williamson amp which use the 807. Quote Link to comment Share on other sites More sharing options...
molecularman Posted August 3, 2003 Share Posted August 3, 2003 I think think uncle ned means the pin layout of the tube, base. But I have been wrong many times Shane Quote Link to comment Share on other sites More sharing options...
Marvel Posted August 3, 2003 Share Posted August 3, 2003 From the above comments, I believe you guys are right about the pin layout and not the biasing. Marvel Quote Link to comment Share on other sites More sharing options...
ben. Posted August 4, 2003 Author Share Posted August 4, 2003 Gentlemen Thanks for taking a minute to respond. I'm kinda thinking out loud on this front. I am a raw newb when it comes to building anything, so I'm not sure if I'm going to go ahead with this from scratch, or maybe just cut my teeth doing a mod, even just a pinout rewire. Are SE designs easier to build? My assumption is that they have fewer parts and simpler topologies. This IS an assumption, however. Anyway, thanks for the leads.
