Hello,
The panel meter (plate voltage 0-3Kv) of my Linear amplifier fl-2100Z is
broken.

We often see requests for analog meters, which are fragile and hard to come
by, to say nothing of expensive. If the objective is to refurbish a vintage
amplifier, then probably the best bet is to find a junk amp to cannabalize
for parts.

But if the objective is to actually -use- the amp, then a micro and an LCD,
along with a little design work, can lead to a meter that is more accurate,
more robust, and cheaper than the original.
