Geoff mentioned the solid state 'relays' are obsolete. It should be possible to find a suitable replacement. If you have plenty time to Google.

Can be a problem. Have you tried an obsolete semi-conductor broker for them? It's unlikely they were specially made for a company the size of Gledhill.
Not trying to tell you your business, of course. ;-) But most of these things can be found - at a price.

I am not so sure any semiconductor is ever obsolete as such: either there is a plug for plug better version, or someone still makes it.

How far does that go? I'm assuming that physical mods would be OK, but changes to the function of the circuit wouldn't?
If you've a resistor that keeps damaging the board underneath, would it be an inappropriate mod to use a higher wattage component and let it stand higher off the board?
What about repairs - if some tracks are damaged, would you be OK linking past the damaged areas?

Higher wattage would be OK, changing the value isn't
Of course - it's not changing the function of the pcb

Yes, I bought two off him in 2009. What few he has left he wants to sell as part of kits...I think he's cornered the market.

I remember when I used to spend all day making front panels for one-off bits of electronic interface gear for the firm I worked for. Very satisfying, neatly Letrasetting and lacquering it all. Done properly, it looked like it'd been "properly" machined and screen printed.

That's what I've often found. But sometimes if you keep looking you'll get somewhere that does them in smaller quantities.

RS do a kit for etching and colouring anodised ally panels. So you do the artwork on the computer. The results can be stunning and very durable - although the colour choice is limited.
