HP 423 detector

Hi guys. I have a 'dead' HP 423 (neg) detector.

Are these fixable and if so are replacement diodes available at 'ham' prices.

I guess it may be possible to graft some cheap diode in there to replace the broken one but I suspect someone out there has fixed these things before, to at least approach the original high specification.

I thought I would ask before 'bodging' a fix Hi.
