AUDIO AMP PAGE
Listed below are summaries of several audio amplifiers that I have built or restored. Some of the summaries have links to pages containing more information on the particular project. All links go to additional pages that I maintain. All projects presented have been built, tested, and most are still in use.
A compact assembly
with power output tubes recessed Into the chassis to provide some extra
cooling. The chassis was 7 X 9 X 2 inches and housed both the power
supply as well as the power amp and preamp. This project was never
fully completed. However, it did work up to the pre-amp. I just never
got a pair of good 6L6s to take it all the way to completion.
This is my version of the 'Darling' amp.
Power is a little less than
two watts per channel using two 1626 triodes in parallel per channel.
The preamps are 6SN7s. This particular amplified uses two Magnaquest
output transformers which may end up getting replaced with more
reasonable iron. The Magnaquest transformers are capable of much more
power and would be excellent in a larger amp. This amp is available.
A 6EM7 is used as the power amp and driver.
The pre-amp is a 6SN7
connected as a SSRP amp. Two of these were built. One for each channel
of my stereo TV. I would hardly call this a home theatre, but with
efficient speakers it is a major improvement over over the tinny audio
from the stock TV. Both amps, power supply and cables available. Best
This was a major success in resurrecting a very nice,
integrated amp. 14 watts per channel. Restoration included replacing
the power transformer, the filter capacitors, the filament hum
adjustment pot, two tube sockets, and a few resistors in the pre-amp
section. This amp is currently available. I will accept the highest
offer over $300.
The EICO 2536 incorporates the same basic, integrated amp
used on the
HF-81. In addition, the 2536 includes a very nice FM stereo tuner.
Restoration was more than worth the effort. All that had to be replaced
were the power supply filter capacitors. This amp is availble. Best
