It looks like is has one channel ? Can you make a photo from underneath ?


These are my own build tube project from scratch ( except the diagrams ;) )
On the left an old Dual turntable, in the middle the "Phonodude" by Triodedick.com PreAmp and in the far right the Bruce Bender 6N1P Headphone amp.

Accidently saw a downloaded schematic fron Italy of a Triodino II, an ultrasimple SET, 4W/channel using just two tubes (three if used with rectifier tube).
Had the transformers; Danburys DB1090 for OP-trannies and a Welter Electronic (DE) N3/1 for mains X-former. I also had a Hammond chassis that I had drilled for a tube X-over, but now had to "redesign" for the Triodino. It got rolled twice with green Hammerite.
Found the 5998A somewhere (labelled IBM - good for digital sound :spin:).
Some comments on the design: I installed an iPod dock so I could use it w/o players (except for the tiny iPod), the IP-connectors are mounted close to the front to minimize hum pick-up. That's why the mains switch is mounted on the back. And I finally got use for my LEDed knob.
It's a really good sounding amp, perfect for my horn speakers with fullrangers from Hungary (www.sonido.hu).
