[Amps] AMPS

[Harold Mandel]

The GM3SEK and WD7S Triode and Tetrode Controller boards,
when suitably integrated, when properly adjusted, serve to 
protect tubes and power supplies in a much faster time frame
than fuses.


Incorporating these modules into amplifiers is a chore
involving careful measurement and alignment, but the
end result when testing the protection circuitry is
satisfying.

So far I have incorporated three of these units into 
projects here. Each of the devices has their quirks
as do they their merits. A full set of protection
schemes is worth every penny spent, as one glitch
can wipe out tubes we spend thousands of dollars on.
