Countless bass tracks in the ‘60s and ‘70s were recorded with them. If you’re a fan of the Motown sound, you’re listening to the bass grooves of a Portaflex. Sounds mean with the Microtubes bass distortion pedal as well.

This mixer was hand built in the early 1960's for a radio station back east. It is a 3 channel (to 1) and the mixing occurs inside an actual mixing transformer (UTC LS15x) , then there is around 80 dB of makeup gain. Its built with the absolute best parts of that time including UTC LS transformers and Daven stepped attenuator (silver contacts) .

1950's Cinema Engineering line amps. These microphone preamplifiers (they are actually line amps) are my all time favorite and have insanely low noise floor ( -95 dB below max +24 dBM output), all the tube vibe you could hope for when driven hard, and very clean and beautiful when you hit them softly. Very rare and sought after, they are a great addition to the arsenal at World Class Audio.

My friend Jos gave me this amazing 1940's pilot light, which is basically a Nuclear symbol, perfect for this custom rack of AX 102 tube line/mic preamp modules.

1959 Magnatone Tonemaster amp! amazing and minty 

Heavily modified ATC SCM200 mains- Raal ribbon high frequency drivers, lambda TD6h mids, and the DEQX system for crossover and phase, group delay and frequency tuning make this system one of the most accurate in existence. 

Cinema Engineering 1950's 4032 passive EQ with tube line amp make up gain stages!
