Hi...
A matey who works at an audio software co has asked me to help them build a tube measuring device in order to take down properties for some dsp modelling action. The idea being to have a multichannel high voltage, high power DC coupled amp where u can plug in dif tubes to read of their stats...
Requirments are as follows:
Channel 1 (High power):
0-5V input -> 0..500V output (gain 100x) Current capacity 200 mA
Channel 2 (Medium power):
0-3.5V input -> 0..350V output (gain 100x) Current capacity 30 mA
Channel 3 (Low power):
0-5V input -> -40..10V output (gain 10x, input offset -4V) Current capacity
10 mA
Also 6.3V heater supply at 3A.
Has any if u toob gurus done anything similar or have any info for me to go on...?
Cheers :thumb:
