VACUUM TUBE OP-AMP USING LOW VOLTAGE TUBES?
I would like to build a low voltage op-amp circuit for an analog computer. Can it be done ? I would like to use tubes in the 12 volt range. The idea is to construct an analog computer like the Heathkit EC-1, but using low voltage tubes for the op-amps. The EC-1 is very expensive, and hard to find on Ebay etc. Any ideas?
Thanking you in advance,
