Vox AC15 clean channel inspired guitar amplifier
Some pictures and the schematic of a guitar amplifier i have built. It is based on the clean channel of the Vox AC15, but has 2 x ECL86 instead of ECC83 + 2 x EL84. I prolonged the tail of the phase-splitter because i had the 42 Volt tap on the power transformer anyway. I replaced the bright-switch of the AC15 with a one-knob tone-control.
It sounds good (no hum, low hiss) but has a lot of gain. In hindsight i could (should?) have used a tone control with more insertion loss. Greetings, Robert |

Very impressed.
What speakers are you planning to use with this? Best Regards Rob |

Re: Vox AC15 clean channel inspired guitar amplifier
Hello Rob,
Thank you for your compliment. I use the amplifier with one Jensen C12Q-8 speaker in a Palmer cabinet (they come without speakers). The cabinet now houses two Jensen C12Q-8 speakers but the connectors on the back permit hooking them up seperately. For some more info (in Dutch...) and pictures, see: http://otl800.blogspot.com/2017/01/g...2-x-ecl86.html Greetings, Robert |
