6197 6CL6 Headphone OTL Tube Amplifier
I am proud to offer this sweet little headphone amplifier for your consideration.
This is a new design and build, completed in July 2012.
What inspired this amplifier was a repair job I had done on a Singlepower
unit and my love for the clarity of the 6197 tube. However, this is NOT the
Singlepower design, but different circuit.
I have used the 6197/6CL6 in other amplifier efforts, most notably my so-called
"Spud" amp renowned for its excellent midrange character. In this design, I
use the tube triode-connected in what is essentially an SRPP circuit.
The design uses a CLC supply filter and split heaters for low noise.
Amplifier is dead quiet.
Design "low" is optimized for 50 ohm headphones and will drive to over 600 ohms
without issue. Easily drives my Sennheiser HD380 (52 ohms) as well as the
HD650 (300 ohms) when sourced from a CD deck level input.
Input impedance is 100K. Volume control, 1/4" headphone jack, and input
connection are on the front panel with a standard IEC AC power input jack
on the back. Input is 115-120VAC 60Hz.
Dimensions are about 11" x 8".
Although this is a fresh NEW build, I always rate at 8-9 because in any hand
built unit, one can always find flaws.
You get a quad of NOS 6CL6 and a quad of NOS 6197 with the unit. Let me
know if you need a power cord (like the computer type) and I will include it.
Price and Payment:
Price is firm. Worth every penny.
My preferred payment is Paypal, so there is no extra charge for you to use that.
I will also accept Postal money order or a bank check.
Personal checks from previous clients are acceptable. Please contact.
Shipping to "the 48" is a flat $24 even though the shipping may show differently
on Audiogon. Other destinations should check USPS services or contact me.
Unit will pack in bubble wrap for a safe trip via USPS ground insured. I have
packed and shipped a lot of amps so they arrive safely. Priority mail upgrade
is available, just let me know you want that.
