I think can do it. What I would end up doing is building the amp to handle 6V6 tubes but keeping the specs low enough to also be able to handle 6K6 tubes as a drop in replacement. It will be cathode biased anyway, so you're looking at potentially being able to run 6L6GC, 6V6, 6K6, KT66, 5881, and EL34 tubes in any combination of two you wish, not to mention EL84's through a THD yellowjacket or equivalent Octal/Noval converter device. I'll tinker with this idea a bit. Either drop-in replacements running higher-powered tubes at lower levels (which would result in lower wattage, possibly) to make sure everything can just be dropped-in, or some kind of switch for each socket to run the tubes at different specs. That sound good?

Yeah, please pm me a price. I am seriously interested.

As soon as we have one, you'll be the first to know. We're shooting to have a working prototype finished before the second week of December. We should know how much its going to cost in a couple of weeks, because starting tomorrow we're going into hyperdrive with R&D.

Next time I get a sum of money, I'm going to build two CAT-5 connectors, hook up audio in/out on each one, put our buffer design before the output of one end, and see if the footswitch effects loop will sound the way people would want it to. Watch... this idea is going to catch on, everyone is going to copy it, and we'll start seeing production CAT-5 cables rated for audio.

Honestly, it is insane. Could be one of the best ideas I have heard of in a while on a classic tube amp.

Hey, Jëss. Nice to have you back!

So I came in here to hear more about your amp project... I'm looking into getting an amp in the next month or two...

Dual channels/switching and effects loops are big things for me. A built in boost would be nice, but not really a necessity. If I understand what you're thinking with the CAT5 cable, that would be amazing. Instead of having one cable running to the input, one to the fxsend and one to the effect return, simply one cat5 cable... I

I know you don't have an official price, but what sort of price range are you thinking?

There will be a switchable buffer after the footswitch's loop, but not exactly a boost circuit. I can probably add a micro amp clone with volume and switch into the footswitch, post-loop but pre-buffer as a custom option. It would boost the signal a bit going into the power amp.

I really hate to quote a price right now, but I'm estimating it be around the $800-900 range.

Ah no biggie... I have a boost pedal.. I just always like the built-in amp boosts.

Cool. I totally understand the price is extremely flexible. And we're talking for just a head right?

Definitely looking forward to hearing what you've got in the works.

Keep us posted.

Yes, that price is just for the head. We may make combo versions as well, which would cost a bit more.

I'm looking forward to getting this thing built. I'll keep everyone as posted as I can.

So, my estimate was about right. We are definitely looking at the $800-900 price range.

Also after doing some research we're learning that some of our ideas may be completely pointless in this amp. Too tired to really talk about it right now, but we are having to make a choice between two features, because it would be counterproductive to include both.
