This week I put in my order to Signal Tranformer for a new 24-1A transformer.  Believe it or not, despite the passage of 40 years, Signal will still custom make just about anything they previously made, for a price.  The cost of the transformer itself is about $103USD – not cheap, but according to Signal it will be identical in every way to the originals used in the 70s, which would be handy since the TVT instructions call for a 24-1A as the preferred unit.

The boards meanwhile are pretty much done.  Here they are (please forgive the lighting:

And stacked together:

Now I just have to hope that when I apply power, it works.  I should note that I kind of failed to follow the instructions – the instructions have you build the unit in a particular order in order to safely test things as you go.  For example, the instructions for the mainframe have you build and test the power supply before installing other components like the RF modulator.  This is to minimize the risk of serious damage if something is wired wrong.    I could help myself perhaps by dismantling those parts.. but I think with a good, thorough checkover (several times) I’ll feel pretty confident about plugging in the mainframe at least and working my way up.  Cannot believe I’m so close to being finished!  What a fun ‘little’ project!
