NEW ITEMS ADDED AT TOP. Buyer pays shipping from Dallas, TX. Prefer N. America as I’ve had some problems shipping to Europe/UK in the past.

What doesn't sell goes on Reverb & eBay.

Photos below.

The list:
  • Pair DBX 163X overeasy compressors. VG condition, work perfectly. $200​
  • Collins 212Z-1 germanium remote broadcast microphone amplifier. Previously owned by Voice of America radio (sticker still partially visible). Great cosmetic condition. Worked with some scratchy pots last time I tested it a couple of years ago. Now I seem to have misplaced the cable. Planning to put it on eBay but if someone here wants to put a new jack on it and do what I believe will be the minor maintenance needed on it (clean pots, maybe replace a cap or three), I'll let it go for $500 (currently priced at between $900 - 1200 on eBay and Reverb. Not that that means anything). Cool unit. Just can't get around to it.​
  • Pair of UTC P-1 mic to grid input transformers. These are UTC O-1s in a bakelite housing with an octal plug. Exact same transformer. $200 pair.​
  • 80s/90s ATI Model EM-1000 "Emph-a-Sizer" signal processor. Gate+Comp+EQ. Rare little unit from the ATI micro-amp line. Clean, 5234 based signal path. I have the manual, which is more of a brochure. Lots of tweakable trim pots inside, which I never messed with. $375​
  • Rane DMS22 dual mic channel, with power supply. Stereo switchable. Sort of like two Rane MS-1s with EQ and an output level control. I think these are SSM2015 based signal paths, which sounded good to me in the handy little MS-1 (original, not A, B or S). $225​
  • Rane MS-1 mic amp, with power supply. $120​
  • Power Designs model 6010 60V variable bench power supply. Accurate voltage across the range, as shown in pictures. Heavy. Shipping won't be real cheap. $90​
  • Samson 5 channel headphone amp with power supply. $40​
  • Pair of Cornell Dubilier decade capacitor boxes from around the 1940s. Both tested and surprisingly accurate. Stray capacitance with no cap in the path is about 85pF on one and 180pF on the other. Almost fully accounts for the difference between measured and nominal at all settings. Very cool units. Both for $40.​
  • Pair AGK D-160E dynamic omni mics from the 70s. Work great. $140 for both.​
  • 1930s/40s UTC Model 3A Equalizer; same family as Cinema Engineering/Langevin/Altec units (40s - 60s) all original (knobs may have been replaced but with RCA Viz knobs), ready to go - $975
  • Triad HS-29 interstage transformer for accurate Pultec builds. OEM model number, but it’s a real HS-29 (label and DCR/inductance measurements identical; used one in a Pultec build – see pictures) - $330​
  • Pair UTC B-4566 input transformers for Raytheon RM-10 (1940s – part no. 291-B-107A). These are identical in pinout and measurements to 1st gen, sandcast UTC A-11s. See diagrams below. - $220/pair​
  • NIB Thordarson 27S08 (Mil-T-27A) steel jacket output transformer. 20k (split 10k-10k): 600:150, +30dbm (1W), +/-1/2dB 30-15k. Cap coupled SE or P-P - $150​
  • UTC O-12 input transformer for 1176 builds - $120
  • ADC 323D output transformer. 10kCT:600, 150, 16, 8, 4 (P-P 6V6/6F6) +40dBm (10W) +/- 1/2dB 30-15k – excellent period-correct iron for BA-6, Sta-Level & other P-P 6V6 compressor/limiters - $240​
  • Pair Freed line/mic-grid input transformers. 600:50k, tested 20-20k w/600 source R to both unloaded and 50k load. Ouncer size. $80 pair​
  • Pair RCA mic-grid input transformers for MI-12241 preamp and others. Same as UTC N-6565 (I have one of those I’ll sell if you need 3 channels); measured these in similar fashion as the above and they are nearly flat 20-20k with both 250 and 600 source R. So better specs than the preamp they were originally part of - $100 pair (3rd UTC version available for $50)​
  • Pair Triad A-65J SE or P-P output transformers (more available). 15k:600, 150, 30-15k 100mW (+20dBm); can sub for A-24 or A-25 - $140/pair​
  • Original RCA 86-A limiter meter. Working properly - $150​
  • NIB really unique pair round Triplett VU meters. $180 pair​
  • Pair clear bezel Triplett VU meters (I may have one more pair). $120 pair​
  • NIB pair Ideal Precision trapezoidal VU meters - $100 pair​
  • Other individual vintage VU meters (Simpson, Weston) $40 each (see pictures)​
  • Original, unused Vactec Vactrol VTL5C2 (2 available) - $8 each​
  • More coming
