Man the Titan 910 is crushing it! This thing sounds incredible. So much so that I looked through my spread sheet of transformers and think I have found the next project. The Saturn 50 amp was a really great amp. I have enough to make one killer 50 amp with all MagneQuest iron.

What tube would you like to see an amplifier in?

Should have posted this yesterday, but having server problems wasted much of today! Cosecant was born 8/6/2003. I remember plugging it into my silly white MacBook computer with a 80G rotating drive and probably 10 albums ripped. Played the first track and got super excited. Here's the first and the last Cosecant that's still available.

I have a couple of pre-production studio grade Cube Tube DI with re-amping circuit. These have a wopping 8.75vrms (25.2Vpp) input before clipping. The single 12B4A drives a custom CineMag output transformer. If you have questions go to the website and send me an email! Thanks Gordon

Update, should have a pair of these Gemini Twin v #3 done soon. Crazy amount of work went into these to make them perfect. I am also waiting on the last pieces for the Titan 910 amplifiers. This is a one of a kind amp that I am really excited about. But today I finishing up building 3 of the Tube DI units. These will be available DIY in the future. In/Thru, Out TS, XLR, Variable PAD and RE-amp XLR. Single 12B4A tube drives the custom CineMag output with 20Vpp input!!! Anyway here's the Gemini from top down.
