CUSTOM BUILT EL34/KT77/6L6GC SWITCHABLE TRIODE/UL SE TUBE AM À SAINT ANDRÉ LES VERGERS

Selling my custom built EL34/KT77/6L6GC/6P3S-E Single ended class A Triode/Ultralienar tube Amplifier. I have built this amp myself based on a Douk Audio chassis but with some important design improvements and better components as follows: - Audiophile coupling caps: Jantzen Audio superior Z 1200V - ELNA Cerafine cathode bypass caps and Vishay filter caps - Takman(Japan) and Allen Bradley carbon composite resistors in audio critical circuit spots - Triode / Ultralinear switches (original design is only UL) - Cathode bias adjustment knobs with resistor networks in parallel (inexistent in the original design) Adjustable bias allows for usage with a wide range of tubes. It is thus a great start for tube rolling. The amp is offered with the following tubes: A pair of JJ KT77 power tubes A pair of 6P3S-E power tubes A pair of 6H8C preamp tubes 1X Svetlana 5U4G / 5C3S rectifier tube 1X 5C4S / 5Z4 rectifier tube Important:  The amp should not be power cycled while hot/warm to avoid cathode stripping and rectifier sparks in order to preserve the life of tubes. UL/Triode switching should be avoided during operation Bias switching during operation is okay in this configuration but should be avoided. Single ended triode amps are low power and highly recommended to be used with high sensitivity 90dB+ speakers Selling due to involvement in several other tube amp projects.
