For Sale:
C3G OTL headphone amplifier (DIY)

Will Ship To: Anywhere

For sale is one of my babies, an amplifier I never wanted to sell...
But I simply have too many amps around and I can't give all of them the playing time they deserve.

This is a SET OTL amp based on the german C3G pentode (wired as triode). In this build pretty much everything is custom made...

from the chassis (Walnut Burl over cherrywood + 8 mm aluminum top plate) over the custom mains transformer and
the custom chokes to the white Delrin volume knob.
Only very good parts were used: Siemens MKV (paper in oil) output capacitors, Sanyo Oscon +big Mica, Kiwame load resistors, a Noble pot
(detented!) and an all-MKP psu (CLCLC) with a 5R4GYB rectifier tube. Mains voltage is set for 230V only, sorry.

It plays all kinds of music very nicely with amazing resolution and a punchy bass (on high impedance headphones preferably
- I am using Sennheiser), it is hum free and has many years of service to come.

Built quality is as you see in the pictures... for questions please send a PM ( provide an email adress then)

Asking 550€ plus shipping.



This is not the first self-built amplifier I am selling and I always had very good feedback.
