What started with the desire to build a simple two tube 2W tube power amp resulted in a dual mono constructed integrated. Each channel has a power tranni, rectifier tube, choke, filtering caps and 6EM7. What is shared is the 4S Universal single stage preamp. The 4S Universal will accept any 12Axx tube with no bias adjustments required. This includes: 12AX7, 12AT7, 12AY7 and 12AU7. True plug and play allowing the user to customise the tone of the amp by trialing different tubes.

The colour is Sungold and is a tough Epoxy Enamel paint. The base, Mirbue Asian timber. The pot is Alps Blue velvet and follows the preamp stage. The knob, 4oz of solid brass with a black chrome finish. Signal caps are Jensen copper, paper and oil and Solen. Hook-up wire is pure silver. Amp has not been completed as yet.
