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.

Happy New Year All!
Currently working on finishing a couple of Tube DIs. Also thinking about bringing back the Gemini Twin 45/2A3. Also a new 300B amplifier is in the works. I know finish the phono stage and preamp :)

Happy Holidays All! I am busy working on a product for another company. But I got a call from Echo Audio today about the Twin amplifier. I made only 2 pairs of this 300B parallel output with a pair of 300Bs, 6072A input tube, 6SN7 driver and 378 rectifier. This pair was made 11/1994 for CES 1995. When I was doing CES shows (16 so far) this time of year was crazy. You usually had to ship everything by the end of the month of DEC and not early because of shipping anything before xmas was well unlucky. Here they are if your interested in the build.

The Wavelength Audio Twin V1.4 mono amplifiers are single-ended triode designs built for pure, natural, and harmonically rich tube performance. Using directly heated triodes with no feedback and premium output transformers, they deliver exceptional midrange realism, dimensionality, and musical flow....
