Thinking of building a 6v6 powered Matchless Clubman

[jcat5503]

I've been wanting to build a 6v6 powered Clubman for awhile. The pentode ef86 second stage seems pretty cool. I heard an el34 version that sounded killer but was stupid loud. I think the 6v6's would offer a little less volume. Plus, I love the way they break up..

I've got a schematic. Any changes i should make other than the obvious stuff? Any suggestions on transformers? I will have to create a layout as well. Some help with that would be much appreciated

Cheers

fender deluxe transformers would probably work nice.
i built a clubman channel on a jcm800 type amp, cool sounding preamp.
i bet it would sound nicer in front of the cathode biased power amp.

6V6 is still going to be very loud, just less so

I suggest a 18W set of iron instead of Deluxe, the higher primary Z and the lower B+ will scale down the original better.

If using the 18w transformers, I would use the ez81 rectifier of convert it to solid state

Most 18W PTs have a 5V tap on the rectifier filament winding.

I know cause I'm currently building a 6V6 amp with a GZ34 recto using 18W iron.

I know the Classictone and Trinity do, at least

Interested in this as I have a 18 watt set of iron
and also like the ef86 idea with 6V6's.
Just finished a 18 watt ef86 with el84's and really like it.
What schem are you getting ideas from?
This is one I have looked at not sure how accurate it is,
power supply seems similar to HotCat/Straycat.
I read that someone changed to 6V6's in the straycat after changing from 270 to 470
so possibly change the 330/10watt to 470's for 6V6's.
Make any sense?

Why not use the higher HT PT that a 6V6 would normally use but use the 18w OT for 8k verses 6k for 6V6.

Also Turretboard.com has the 310-0-310 PT used in their Supro kit and they use an 18w Marshall style OT at 8k with this PT. They are made by Heyboer.

I agree Mark
Wish I had a higher rated PT lying around. Kinda like to use what I have.
Just bought my kid a car and insurance and it looks like the wife thinks
its coming out of my hobby money.
Possible to go with a SS rect. and hit a higher B+ safely?

Might consider trainwreck transformers. That way you could throw el34s in it if/when you wished it were more powerful. Nothing more annoying then spending a lot of money and time building an amp and realizing that its not powerful enough to use in certain situations. Triode electronics has a very reasonable priced set. I know I'm not building anymore 15w amps for myself, I hate showing up at a jam and the amp not able to keep up. Just my 2 cents.

Sure use what you have to work with it will still be a good amp.

Yes the TW transformers such as Express 600vct with 6k6 OT would work well but might be loud I used the MC set from Triode and love the tone I'm getting. The PT is an overgrown sucker though.

Use that extra input on the phase invertor and build a matchless chieftain channel.
