The
Tube Imp - Mini Tube Tester
Moth group are pleased to announce the availability
of the Tube Imp
mini tube tester. Designed and built in the UK, the Tube Imp
measures
the steady state current, gain and transconductance characteristics
of
any B9A double triode tube with the standard ECC83/ECC88 Footprint
Operating at 12VDC from the included external
power supply, the Tube Imp offers matching and parameter testing
of a range of commonly used
double triode valves at a price that is affordable to individual
valve equipment enthusiasts as well as retail outlets small
OEM concerns.
