Single ended 6L6 amp - unable to find the kit - help, please
« on: January 31, 2017, 12:53:40 pm »
Would like to build a SE amp like a 5F1 but with a 6L6 for higher output and more headroom.  Have been looking but can't seem to find one.  Is there one somewhere in the Hoffman list that I am just missing?

Follow the 'Tube Amp library of information' link at the bottom of this page. Hoffman's 5F1 is at the top of the list. You may need a bigger PT and OT but everything else is the same as the 6V6 version.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

5F1 or AA Champ, with "Champ/DeLuxe" PT, plus a 5K "6L6" OT from one of the hot-rod transformer shops, is all you need.

No special wiring? just a 022772 PT, 5F1 loaded PCB and WSE15 type OPT and I get a 10- 12W Champ? Seems too simple.

> No special wiring?

If you just want a little more power, you just use a bigger "engine and gears".

My mom bought a Mustang. Choice of 100HP Six or 200HP V-8. It was essentially the same car either way. (Actually if you got the Eight then Ford gave you the less-cheap wheels and brakes. But the Six's brakes were like a cardboard cabinet on an amp-- too-too-cheap.)

why doesn't some make a SE 6L6/kit? Is There something I am missing? Should I be looking at another kit that is already available?
