Menno van der Veen project 6 guitar amp with tone control and a double ended class AB power amp with 2x EL34.

The double ended class AB output with power supply is finished. Preamp and tone control with tubes will be realized later.

The design is based on project 6 from Menno van der Veen  link to his website . De power and output transformer I have bought from Menno van der Veen for a reasonable price if we take the price for a good output transformer as an example from other companies. The sound is as expected verry good, no noise, no hum. I added a power choke to filter the power to the ECC81 and the future preamp tubes. I also added protection 3000V-0,2A diodes from de anode of the EL34 to ground. The two EL34 end tubes, a matched pair, are manufactured by JJ and the ECC81 is manufactured by Groove Tubes. Resistors are metal film 1%, electrolitic capacitors power supply 470uF-400V, audio capacitors metallized polypropylene film type ECWFE from Panasonic, audio electrolitic capacitors aluminum polarized.
