Now available exclusively from Old Colony in the United States! 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 12VAC 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 and small OEM concerns.
