I'm looking forward to our upcoming DCHFG rummage sale to find new audiophile homes for items I'm not using anymore!
I've come up with some prices but I'll consider any reasonable offers -- I hope to not have to bring any of this stuff home.
See you next Sunday!
Volti Audio V-TracII horns, pair, without drivers. Originally a replacement for the midrange horns for Klipsch Belle and La Scala speakers. They have a 2" throat and are hand-built of wood. They were designed to be used with BMS 4592ND-Mid midrange drivers but can be used with the original Klipsch drivers, or probably with any horn driver with a 2” throat. The current price new is $1,599, but I’ll take any reasonable offer!
AR 3A Speakers. These were constructed probably in 1972 – I purchased them used and completely recapped the crossovers with Solen polypropylene capacitors, replaced the resistors with non-inductive ones, cleaned the level-adjusting rheostats, and replaced the speaker grills with new linen. All the drivers work. These were the speakers of my dreams back when they were new, but somewhat beyond my price range at the time. I’ve satisfied my curiosity about how good they sound (which is excellent!) but now I think it’s time for someone else to enjoy them! I’m asking $999.
Emotiva A-100 Amplifier -- $149.
Emotiva A-150 Amplifier -- $199. These Emotiva amps are real workhorses and are useful in all sorts of applications. I used to use these with some tri amped speakers, but I’ve replaced them with some more modern class D amps and don’t need these any longer.
Nobsound Class A Amplifier with new Edcor output transformers. These use EL34 output tubes in a single ended configuration. I bought this as a kit out of curiosity about how single ended class A low power tube amps can sound. The completed kit had some problems – output was only about 5W and distortion at 1W was about 1.5%, and frequency response was pretty limited. I’ve had a lot of fun tweaking the circuit, but probably the single best mod was to replace the stock output transformers with Edcor transformers designed for single ended class A amps. It also now uses fixed instead of cathode bias, allowing for better fine tuning with individual output tubes, and, I believe, sounds much better. Now frequency response is down 3dB at about 10Hz and 40kHz, power output is 8 to 9 Watts, and distortion at 1W is 0.5% or better. A key issue is the Edcor transformer, for some reason known only to Edcor, only offers an 8 Ohm output tap, so if your speakers require 4 Ohms this might not work (although I am including the original output transformers which do include a 4 Ohm output). Obviously, this amplifier will require some pretty efficient speakers to really shine. I believe this amp sounds as good or better than any low power class A single ended amp out there! I’m asking $400.
Teak CD-P650 CD player. This device has a built in DAC, or you can use your own external DAC via an optical toslink output. $149.
Kenwood CS-4025 20Mhz analog oscilloscope with probes. This scope is perfect for a wide range of audio applications. It’s served me for many years, but now I’m using a range of digital scopes (which in fact were considerably more expensive than this analog scope!) and I don’t need this one. I’m asking $100.
Behringer CX-2310 analog active crossover. This device is a stereo analog active crossover that allows setting speaker crossover frequencies. It also has a mono subwoofer crossover that can be adjusted. The only limitation is it only offers 12dB/octave Linkwitz-Riley crossover slopes. This would be perfect for a bi amp speaker setup with active crossovers, or for experimenting with speaker crossover frequencies with the aim of establishing parameters for a passive crossover. I’m asking $100.
