Aaaaal righty, then. My build is officially paid for. The plan is- four 6L6 tubes, 100 watts, a cage that will hold the Broughton S300 on top with room for the tubes to vent and enough space for the S300 transformer to not present any problems. A lot of thought went into this. There will be a switchable LPF @4.5k, and a switchable HPF @80 hz. FWIW, to further illustrate Micah’s patience and flexibility here, i think i have something like 30 emails towards this. I don’t know if you can approach this sort of customer support with anyone else and get this type of quality anywhere. To be sure- I love my UltraLinear; i don’t know if it can be improved on. I like it enough to commission this second custom build. My intention was to make an all tube amp without any tone controls; a straight wire challenge to my Baby Sumo, Jad Freer CODA and Jule M700 Class “D” and “G” amps. This build is obviously geared towards the SVT but more refined. In addition, this amp can be used as a stand alone. It should crush.
Interesting build! I'm assuming that you prefer the tonal response of 6L6 tubes over KT-88's...
