Dual-Channel Tube Compressor Recalls the Vintage Audio Gear of Yesteryear
Jun 11, 2018
The original Altec 436C was a three-tube circuit. Revolver uses a solid-state sidechain circuit to replace the 6AL5 tube detector used in the Altec, though it retains the same 6BC8 input and 6CG7 output tubes. There are many dual triode tubes that can be substituted, as Retro has a vast NOS supply of American-made tubes (primarily because they were popular television tubes).

I’ll begin this review with a confession; in over two decades of mixing albums I’ve rarely mixed through a bus compressor. Why? The more I kept hearing that I “had to” in order to get good results, the more I balked at using one. I’d tried out the stereo compressors that I owned and was never quite enthused enough – plus I was getting decent mixes without a mix bus compressor, so why did I have to change my style of working? But when Phil Moore at Retro Instruments sent me his new Revolver two-channel tube compressor to try out, I realized…
