Yeh swing by you can take them with you for a couple of days. I need to start casing them up end of next week.

Cool, I’ll pop over tomorrow evening if that’s OK?

I made the little model pictured above earlier today. However, I’ve now picked up Si’s latest Paradise build and one mistake (of mine) is immediately obvious - there are eight, not six, transistors! Here they are:

And here is the CAD I’ve just drawn:

I plan to make them from black plastic but have run out at the monument. I’ll print a trial one tomorrow and check it for fit.

Sweet, temp matched input transistors for anyone who hasn't made a little insulated house for them.

If you really wanted you house the little groups of five transistors in each current mirror as well. They're not really affected by temp in the same way the input stage is, but what theh hell, I'd be digging the full custom look

Are those the ones either side of the RIAA caps and resistors?

Today’s work:

I like the raised lettering but think the curves are a bit fussy - I’ll do a straight sided one tomorrow and the others Si has mentioned.

I'm digging the curvy one, that looks mint.
