Altec 436c tube Compressor with Mods $1,500
EBAY SELLER AUCTION DESCRIPTION
"Here is an Altec 436c with quite a few useful mods. First of all, the unit has been recapped with new power supply caps, and the audio caps have been hand matched for balance in the push-pull circuit.
The output has been wired for the lower 150 ohm output voltage which comes out directly on terminals 1 & 2; there is also an attenuator output on 3 & 4. This allows lowering the out level to avoid clipping into the DAW. XLR connectors are provided.
The Gain Mod switch revises the gain structure between the first and second tubes and solves most of the excessive gain problems of the original design. It also improves the low end.
The Line Amp switch disables the compression circuit and accomplishes the same result as pulling out the diode tube as instructed in the Altec manual. This allows you to pass signals thru the altec to gain some tube color.
Fast Attack speeds up the attack time a noticable amount from the stock value.
For those who want the authentic hold function feature, that is available here with a switch, and this has the advantage that the release time can be an infinitely variable pot instead of fixed values. Just switch Hold, and the gain reduction freezes as long as you want.
Release time and threshold are front panel controlled.
Unity gain is around the 4 position on the volume knob.
The 6BC8 tube balance is handled with a rear panel control and a set of mini pin jacks which are connected to the plates. Just put a voltmeter on those pins and adjust for the least voltage. This is much more precise than a pushbutton and ticking routine.
The tubes are american made NOS; the diode tube is a Telefunken; a spare set of tubes is included.
Proper rack mount holes have been drilled so that the front panel does not need to be opened to mount the unit."
Gates SA-39 SA39 Vintage Broadcast Limiting Amplifier Tubes $4,225
EBAY SELLER AUCTION DESCRIPTION
"
The Gates SA-39 has all its tubes and all of them have been tested to be in good working order on a Hickok 6000 tube tester. .
The SA39 is in working condition. However, no guarantees can be made on the functionality of the unit after it has been shipped. I only state this due to the fact that a vintage piece of gear that was sold some time ago was working perfectly fine when it was sent, but according to the buyer, it had some problems after arrival when it was used. As I said, it is working fine here and now, but it is in your best interest to know that due to the age of this piece of gear, anything may happen during transit. Insurance is necessary for this item and will most likely not be reflected in eBay's total. This may result in a higher price for shipping than what eBay estimates. The tubes will be removed and wrapped carefully before shipping so that none will fall out during transit. "
Mega Rare Bob Fine Pultec Tube Compressor Limiter Mic Pre Vintage Custom Made!!! US $4,500
EBAY SELLER AUCTION DESCRIPTION
"Ahhh...Mega rare tube "valve" vintage compressor limiter. Circa late 1960's. Made by NYC area legendary engineer and tech Bob Fine. Bob took a Pultec MB-1 tube mic preamp (one of the best mic pre's ever made) and added a compressor circuit to it. Front panels of these were sprayed black with cutout for VU meter added. Really a killer unit. I bought this 10+ years ago from a well known producer. What else I know: Handful of units made. Still in use at Sear Sound (actually got a schematic after contacting the legendary late Mr. Sear). Used by Sonic Youth extensively for guitar compression. The great Sigma Sound in Philadelphia also had some of these back in the day. Also mentioned in Tape Op No. 70, page 40, in interview with TJ Doherty (Wilco, Sonic Youth, Beth Orton, Malkmus, Steely Dan, Jon Spencer, the Killers w/ Lou Reed- others) who says it is a "go to" comp for guitar sounds as it is very fast. C. Robert "Bob" Fine also ran his own studio at one time as I've seen pics of Todd Rundgren and the Nazz recording there, and a pioneer of stereo recording (Mercury Living Presence series) and mentor/associate of Walter Sear. Very rarely up for sale. On par with Neve, Universal Audio, Langevin."

CBS Audimax IIRZ Compressor Limiter AGC 6386 Tube US $1,400
AUCTION DESCRIPTION
"This listing is for a CBS Audimax IIRZ Compressor/Limiter/AGC. This is a classic broadcast unit based around the famed 6386 vari-mu tube. I've sold a couple of these and this is my last one. It passes signal but the meter isn't showing gain reduction correctly (it's functioning in other modes) and levels seem a little funny to me. It's going to need a little going over but it's in great shape overall. Someone added a output control to it at some point but it's a fancy Daven pot and it's mounted out of the way so they did the job right. Includes all the tubes even though they're not pictured. "
