Mini-AC30 based on Vox AC4

[Big_Mike]

This is my version of a mini AC30. It has the LTP phase inverter and a ECC99 push/pull power amp. All parts values were taken from the early version AC30 with integrated top boost. This is the perfect amp for all living-room-the edge-wannabes... ;-)
The sound is much closer to an AC30, because it is NOT based on the AC4 - the phase inverter and power amp are very important for the sound.

Wow, that is awesome!  For your power transformer, what are the primary and secondary voltages?  What filter capacitors are you using for B+ voltage?

I replaced R5 in the PSU with two 100k resistors and a 47uF cap to get a reference voltage for heater elevation.
And I replaced the two 100R resistors shown in the layout with a 100R pot. The amp is very quiet now, no hum and just a bit of hiss if the treble pot is wide open.

Very nice, reminds me a little of an old Dickerson-Maggie or Flot A Tone
