New Display for Pendulum CNT-90 Counter
« on: August 14, 2020, 09:52:22 am »
A recent auction of military surplus in the UK released a number (30 or 40) of these excellent counters (20GHz optioned) at <£500 prices.
However, it's pot luck on condition (and even working condition), and my counter arrived with a slight defect on the display.  The display is bright, but has this odd yellow track wandering about under the top layer of glass.  I have checked and it's within the sealed display module.  Photo attached.  It's not serious, and otherwise the counter looks virtually unused and works beautifully.    It does not seriously impact the readability.  However, I wondered if a replacement display might be available.
Fluke/Tek say it's obsolete and have no spares.  The Pendulum UK agent quoted £575 and I have to return the counter to Poland for the repair.
If anyone has any insight into where I might get a new display at a more reasonable price, I would be grateful.

Yeah, there are threads on this around.  I know it's been done, I don't know if the replacement used was a perfect match.
