I purchased a Vox Escort amplifier a little while back, and it’s quite a cool little transistor amplifier. It’s a simple transistor amp from the early seventies with an IC-based amplifier. It screams when turned up.
Here’s my original post with more information on the amplifier (including a schematic).
Anyway, I thought I might try recreating one, albeit in a different format, ideally one that can run on a standard pedal power supply or a regular 9v battery as a practice amp.
I recently purchased the amplifier IC, which is still readily available at a reasonable price – so here it is, a work in progress. The vero layout may go through some evolution as I play with this. I’m not sure if I will try to fit it in a Hammond enclosure or a small wooden box.
Project Intent
- Create the sound of a small speaker that’s being driven into oblivion
- Small enclosure for an amp: a Hammond or a small wooden box
- No expensive components
- Not mains powered, battery or pedal power supply
It will spend some time on the breadboard first, so I may also tweak some values to suit my preferences and tune it to the enclosure I end up using (whatever that may be).
NOTE: This has successfully been built by Ian, see comments below. I actually made some mistakes and cooked mine…
