Versoul amp is a double single ended amplifier.
Two power tubes cathode biased are wired in parallel and amp works in class A.
Both tubes have own master volume control.
Several type octal socket tubes can be used without adjusting the bias voltage:
V4 tube socket: 6V6, 6L6, 5881, KT66,
V5 tube socket: 6V6, 6L6, 5881, KT66, EL34, 6CA7, 6550, KT88.
Depending on the tubes used the output power will vary from circa 5 watts to circa 22 watts.
Several different rectifier tubes can be used on V6 tube socket: 5Y3, 5AR4, GZ34, 5U4, 5U4G
Pre amp section has two channels and several different noval socket tubes can be used:
Tube V1 tube socket: 12AX7, 12AU7, 12AT7, 12 AY7, 12DW7, 5751.
Tube sockets V2 and V3: 12AX7, however other tubes may be used but not recommended.
Channel 1. One pre amp tube in use V1 with Volume and Tone controls
Channel 2. Two pre amp tubes are in use; V1 and V3 with Pre Vol 2. and Treble & Bass controls.
Versoul amp has an unique effect loop section and is fully tube driven. Both send and return signals
are individually adjustable. Therefore effects using line level and guitar level signals may both used.
Gold anodized chassis is made of sturdy 2 mm thick aluminium and joints are welded.
All components are carefully selected and are very high quality, for example paper in oil and
Orange Drop coupling caps and carbon film resistors in pre amp and effect loop section.
Military quality PEC pots are used.
Power transformer, output transformer and power choke are made by Hammond
Turret board and point to point construction are used.
Head and cabinet are made of solid pine with strong finger joints. Front and back plates
are made of 1/4'' thick birch plywood and making cabinet nicely resonating construction.
Covering is genuine leather also piping, corner legs and handles are leather.
Cabinet is equipped with two Celestion AlNiCo Gold 12'' speakers, power handling 100 watts.
The cabinet has semi open construction, which creates thick & airy and open sound compared to
fully closed or open back cabinets/combos.
Pot knobs are rosewood and inlaid with green abalone dots.
The circuit is designed by Jaakko Turunen and the concept and head & cabinet by Kari Nieminen
