It works!
Audio test was successful, quiet audio in -> loud audio out. Whoop, whoop!
Left/right balance testing confirmed that I had not got that reversed. Only mistake seems to be with the volume pot, as I have to turn it anti-clockwise to increase the volume. I think I will have to fix that 🤔
Other observations are a bit of hiss, and some mains hum from the laptop.
Next, a box to live in and then I can connect it to my RC2040 🥳

The kit soldering and build is complete... Next I need to test it with some audio and then house it in the small tin, or maybe something a little bigger 🤔
Initial testing so far has just been connecting the 2x 9v batteries and switching it on. The power led illuminated, as hoped for!

I have now soldered all the PCB components. Off board potentiometers, audio sockets and power connectors next.

New project alert!
Actually, this project is linked to my #RC2040. I have noticed that the RC2040 supports speech synthesis using allophones. So I need a small #AudioAmplifier - and I just happen to have a kit for one from #Kwelatones, based in South Africa (long story there 😊).
It is a TL072 op-amp based amplifier.
I have only added the 9v batteries and the mint tin to house it in.
Anyways, my first step when starting a kit project is to check that I have all the parts, tick, tick, tick...

The #rc2040 uses the same ROM image format at the #RC2014 (a kit running a real #z80)... So I can put CP/M on this (which is what I'm looking to play with) or Z80 BASIC; but the initial is the Small Computer Monior a #machinelanguage monitor - something like those on classic #retrocomputing hardware of the late 1970's (before machines routinely had disks of other media to enable booting to BASIC and/or CP/M).
