Vintage Gates Sta-Level M-5167 RCA 6386 Tube Compressor Limiter Amp - Recapped. Legendary 1956 (6386) vintage Gates Sta-Level tube compressor. Lovingly serviced by David Kulka at Studio Electronics (one of the best in the business) and previously owned by NBC. I purchased it a few years back for a specific project from the drummer of the band Sweet, who had owned it for his private studio for sometime. It works great and sounds legendary. Nothing else like it exactly, not even the reproduction b...y Retro. It features seven tubes including the magical 3686 tube. I imagine that anyone who is interested in this knows exactly what it is, so I wont bother going on about it. I hadnt planned on selling it ever, but unfortunately, due to a close family member who has been given a short time to live, (pancreatic cancer) I need to rapidly come up with funds out of the blue. Anyway, youll never be sorry for buying this in my opinion. Please do note the pictures for normal scratches and ware. Its in amazing shape for its age. Tubes will be carefully and individually wrapped and separated so everything arrives to you in tact. Thank you for considering a quick purchase. - brad
CBS Audimax II model 443 Vintage classic rackmountable tube compressor amplifier. Really nice condition, sound quality and performance. Cosmetically very nice, a few minor paint marks, see pics.Top of line Freed audio transformers.GE JAN 6386 tube.This unit listed here has vastly improved functionality and sound over the original control circuit design. It now performs a variety of compression as well as peak limiting outstandingly and sonically is full range and with a really lively sound signa...ture. The original proprietary CBS automatic control system has been converted to a user controlled system with variable attack, release and threshold controls which are installed on the unit's front panel. See pics.From left to right, the red knob is threshold, the white knob is attack and the grey knob is release. For faster attack or release times, turn the knobs clockwise. With the attack set almost fully CW, the release about 3 o'clock position, the unit is closely emulating typical factory fixed average timings on the Gates Sta-Level, GE Unilevel, RCA BA25 and Collins 26j and 26u series compressor's RC networks, all of these units mentioned also employed the same configuration of 6386 control tube with a 6AL5 signal rectifier modulated by the amp's pushpull output. Very rapid attack and recovery times can now be quickly dialed in and the tube era Audimax absolutely comes alive like it never could before with the original elaborate but sluggish timing circuit CBS had adopted to try and differentiate their product from other manufacturers competing in the broadcasting market. The threshold knob increases the amount of gain reduction when turned clockwise. Like all of these era classic legacy compressors, once you have your basic settings, you just keep increasing the input gain while the control amp maintains a constant output voltage and things in general start getting bigger, bolder and the attitude factor ramps up. With the attack and release time both set almost fully clockwise, the unit is a effectively a peak limiting loudness monster and super ballsy and responsive sounding. I've owned and used many different classic tube compressors over the past two decades, and with these modifications, this unit easily stacks up technically and sonically against all the similar era far more popular and celebrated compressors and limiters. The Freed audio transformers in particular sound magnificent with excellent frequency response, low end and detail. The variable threshold also allows it to perform gain reduction at lower input voltages that wouldn't have been sufficient to trigger compression action in the original control circuit, further adding to the unit's applicability in differing set ups.The conversion also clears up the original audio input path in a major way. Unlike the original CBS control system, this couples the input signal, as well as routes the dc control signal, through the input transformer secondary, directly to the control amplifier grids. With these circuit modifications, this now rare, and overlooked vintage tube compressor is 100 suitable for pro recording and mixing duties and will also effectively perform peak limiting type compression handling extremely fast attack and release times if desired. The meter that used to drift slowly now tracks the gain reduction at a brisk pace. It's a huge difference in performance and sonics over the original configuration.Also, with the modifications, the tubes V1 and V2, that drove the input modulation source for the CBS control system, are eliminated, and the power supply can now run the beefier, higher plate and filament power consuming 12BH7 output tube. You can still directly swap in the original 12AU7 output tube if you desire. The 12BH7 provides more output current and headroom and is presently installed on the unit.The function control on the right front panel gives readouts of the plates of the 6386 and output tube. Now that the 12BH7 is installed, the readings on V4
