Good Suggestions for Tube Amps under 6k

@carlsbad2 

I may have missed it, but what output and driver tubes will your custom amplifier be based upon? Tube or solid state rectified? This amplifier sounds like an all out effort.

Rogers High Fidelity on their website has a pre - owned EHF 200 Mark II Integrated amp w/ full lifetime warranty! Very high quality, sounds excellent & quite powerful! 100 watts / side pure class A so it does put out some heat. About $15K new. 
 

I’ve had mine for 1 1/2 years & it’s a great piece which I highly recommend. It is substantially better than Mac, Prima Luna & probably any other integrated tube amp under $15 K. Handmade , point to point wired by Roger Gibboni & a small group of skilled pro’s. 

@charles1dad AD1.  Built around the EML tube.

Nice!!!

BTW EML are excellent quality tubes. I got over 11 years of superb sound and reliability from the EML XLS 300b with heavy/frequent usage. I expect the same from my recently acquired 2nd pair.

Elekit TU-8600 and TU-8900 are both fantastic 300b amps; the 8600 with Lundahl transformers has strong reviews from Stereophile and elsewhere. With some patience you can pick up a completed amp on the used market, or you can tackle the build yourself if so inclined.
