Firstly a massive thank you to Piet for enabling all of this.
The first plane that was built wasn't Concorde.....
I have entire faith in this valve unit, today I tried it at the North Notts Club having modified it from the very first trials at the Hankies and although it sounded like a bathroom reverb - I was happy enough.
It has great flexibility and power, the 2 independent valve pre-amps make this so.
The arrangement I now have is one of valve pre-amp - echo unit - post echo valve amp but the unit I've built is capable of changing this arrangement internally, without soldering, to one of valve pre-amp - valve-pre amp 2 - echo unit.
It's also capable of sending the guitar signal straight through, no pre-amp, and 'valving' the signal to and from the echo unit, and much more.
These things I evaluate.
Rest assured that I'm happy with this to the point where I've ordered the master PCBs that I've designed to facilitate the echo daughterboard, to generate the HT and heater voltages, I've also ordered engraved nameplate labels and aluminium enclosures.
When I'm happiest I'll put up sound files.
Piet, you are a diamond.
Watch this space.
