Need Tube Suggestions for Rogue Dragon Monos

@buellrider97 Thanks Mike, good advice. Not JJs, but some other common Russian made - I just don’t remember. 

Thanks for the NOS source recommendation. Now that Brent Jessie closed shop I need a good honest source. His website was primitive at best, but contained a wealth of info. And he was unfailingly honest and helpful.

For class D I can recommend AGD. I’ve had several of his lower powered amps, but not powerful enough to drive the Maggies. He does have some in the same power class as the Dragons, but are 2x expensive. They are excellent amps. Oh, and don't overlook Atmasphere's class D monos. Maybe not quite enough grunt for the Maggies, but more than enough for most others. And Ralph is a good guy. 

My only concern with the Dragons is I believe they use an older output module, which might mean a more severe HF rolloff to avoid filter interaction. And that might be why I’m not getting the air I want. Just guessing about that.

Vintage Telefunkens would be my choice.

Yes , I think Andy would be very informative. I have a Rogue Hera and Rogue M-180 Darks. I put a quad of nos nickle plate Seimens in the M-180’s. I have Sovtek’s in the Hera and can’t afford $2500 for an octet of nos Russian tubes for it. The nickle Siemens definitely give it more sparkle than nos Tekefunkens. I definitely like Ralph’s amps and I have Tekton DI’s ( let the criticism start 😆 ) so they definitely have enough power. Cheers , Mike B. 

@buellrider97 Mike, what are nickle plate Seimens? Are these power tubes? If not, what number ID are they? 

You might want to consider PSVane Horizon for replacement tubes for the Hera. I like their 12AU7's quite a lot. 

Unfortunately the Hera takes 6H30p Russian tubes. There are only 2 brands currently produced Sovtek and E H same tube, same plant. The original Russian tubes go for $2-300 each and I use 8. The nickle plate Seimens is a 12AU7 with silver plates. I’m not sure on todays prices, maybe $800 for four.  The only Psvane tubes I ever tried are the standard KT-88 and one of the more expensive Ti version, they both sounded good. Cheers , Mike.
