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.

..



Hi,
Thank you for your answer.
The digital LCD is another solution, but I wanted to keep the spirit of the
old amplifier.
However, I don't know the value of galvanometer, it is not indicated in the
diagram of the manual, It is written only M1.
Regards
Max
