WTB (UK) Farnell LT30-2 parts, or complete for parts.

Hi All. I have a Farnell LT30-2 Power supply.
I Have had it many years but it has always had the black strip down the left hand side missing. This also holds in the aluminium trim strips so it would be good to fix it. I have also recently lost one of the caps off the ch2 fine voltage adjustment knob.
I am just wondering if anyone has a dead one of these, or maybe the single version that I could buy for parts?

For small cosmetic parts like that you might be best served to get into 3DP...

The knob caps are these: cliff cl1764 k21  https://www.ebay.co.uk/itm/203345146107

I bought an LT30-2 yesterday from Stewarts of Reading. Both outputs would only go to 26.7V and it turned out to be the 47uF 63V on each regulator board was completely open circuit. That's by the by. The chap at Stewarts had other LT30-2 in stock... He typically wants £75 a pop.

Drift of the LT30 isn't brilliant, and I suspect that it could be improved. The voltage reference is a 1N823 Zener fed by a current mirror referenced by a BZX61C5V1. I will be investigating to see if a more recently manufactured (cleaner) Zener helps. Also, the 1N823 isn't being operated at the data sheet's optimum current of 7.5mA.
