6360 as Power Tube for SE amp

psnw_tom · 11th August 2007, 02:37 PM

I have plan to use 6360 / QQE03-12 as power tube in SE amp and like to have some suggestion or may be anyone kind enough to share the circuit and experience you have with this tubes.

I do not have any schematic at the moment but I am interesting to put the tubes in good use. I have 10 of 6360 and think that it might be great if I can put these double tetode in action - SE or PP. I am quiet new with tube, actually have no knowledge relating to electronic.

Appreciate any thought or schematic.

just for a historical prospective -- the 6360 was used as a frequency doubler or tripler and output stage in commercial and ham transmitter designs of the 1960's -- for instance in the Hallicrafters 6 Meter Transverter -- you could use the tube to a few hundred mega Hz

Hi,

Do a search on this forum - I previously commented how I was impressed with this tube when parallel/triode-connected. There was some reservation expressed at the time re screen-grid voltage ratings, but I have no reservations up to 300v+.......

I confess to not having progressed from graphing characteristics; got side-tracked into developing suitable output transformers! These are now completed and very successful too.

My bench is littered with books, papers, and tubes as I swing from idea to idea - impressed with Pointz' triode 6V6s as I also have many of the Brimar 6BW6 (noval 6V6 for which they quote better distortion figures) Recent purchases have brought my holding of 7236 tubes upwards of a dozen and this has caused me to act like the legendary John Gilpen ie striding from the room, leaping on my horse (literally) and furiously galloping off in all directions at once.........

If you pursue the 6360 tube, I can only emphasise the previous post harking to it being an RF tube, and stress the correct use of grid-stoppers.

thank Graeme .....

I actually did read our opinion on the 6360 even some might experience differently.

Even so, I really like to use the tube as power tube by pararelling both plates. What I'm wondering whether I should tie G2 to plate or to G1.

I like small amp with few tubes and I am current very much happy with 12B4A SE amp that I had built. I like the way the amp convey music especially to my taste.

Anyway, I also like to experience with other tubes sound ........

Hi , there was written many pages about this toob some month ago ! Don't go higher than 150v on G2 . I have a pair of PP amps using these as sub of the El84 , just add an 0B2 regulator and wou'll get a

8watt amp
