Tekton Double Impacts

Charles,

Thank You for your valued perspective and I will be looking forward to read about Mac's and your outcome with your Frank's driving mac's DI's and using the MZ2S line stage .Should be quite interesting.

I've read several different takes on the Yamamoto that I have and you are correct it's quite a warm amp even with the very quiet and neutral Siemens c3m driver tubes that the amp uses and without doing a complete circuit redesign I don't have any suitable substitute for that tube.Maybe a lively V-cap coupling cap might change it's character for the better.

After talking to you and also reading several reviews on the Frank's I have no doubt that they sound very good and might be a good choice for me but I can't get past the chrome and I much prefer good ole basic black.But never say never right.

There is a upincoming amp builder and his name is Aric Kimball and his website is Aric audio.com,I've been talking with him about building me a custom 2a3 amp that uses 6sn7 drivers and solid state rectification and also staying under 2k.

Thanks for the link to the tube amp site Kenny. Does he build point to point or with circuit boards? Like the amps and prices. Not a fan of circuit boards in tube amps and thus my question. His amps remind me of Dennis Had’s amps. Dennis builds his himself all point to point wired. Works of art!

Second, Hammond output tranny? I have used them and they are OK, but....
SS rectification is a great way to go with your speakers. Typically SS rectification yields better bass performance. Always exceptions, but in general I have found SS rectification best in tube amps.

Will your custom amp use different output trannys?

Kenny,
The stainless steel chassis of the Frankenstein is actually understated and elegant when seen in person,  it isn’t gaudy at all in my opinion.   The Aric Audio looks interesting and makes me wonder how it compares to the Triode Labs amplifier. I suspect that Aric can build you an excellent custom SET amplifier. The Double Impacts clearly allow  you tremendous flexibility in amplifier selection.

Agree with Bill regarding point to point vs a circuit board and also the output transformer.  Kenny get the best output transformer you can comfortably afford if you decide to go the custom route  (I know you realize this). That choice can literally make or break the success of a truly special SET amplifier.

Electra-Print trannys are great! Can get pricy. Perhaps you can find James transformers on EBay or elsewhere? They no longer make them, but they can be found. They are wonderful for the money.
