This is a brand new, sealed SRS BiasKit 3 tube
amplifier bias setup for EL84. Includes one (1) Mini BiasTool PVT plate voltage tester
and one (1) Mini BiasTool bias current tester, plus instructions on how to
hook up and use the devices.
The SRS BiasTool test adapter is used world-wide by tube amplifier technicians for correct setting of
bias current, a critical measurement and adjustment required when installing new
output tubes in a tube amplifier.
The SRS BiasTool PVT test adapter allows safe, hands-free measurement of dangerous plate voltage in tube
amplifiers- a critical measurement for determining the correct maximum
safe bias setting in any tube amp.
