Hi Joe,

Not true, I have this model of tester, the heater extension unit allows you to select multiple heaters ranges by switching between the main panel and the extn unit giving you a range between 1.1V to 117V for heaters. Quite a good little tester, for testing gm and emission (bad/indiff/good)

I have tested battery valves, as well as some TV valves with honking great heater voltages.

My tester shown in post #2 http://vintagetvandradio.myfreeforum.org/about435.html

This was AVO's first tester and it came out in the 1930's mine is 1947.

Over the years due to the MKI, MKII & MKIII CT160  etc all leaping to totally ridiculous figures (anywhere between £500  - £1000) the two panel has been dragged along for the ride.

I've seen them fetch as little as £50 and as much as £250, mostly around the £120-£150 for a good one, condition as usual dictates. Which makes it the cheapest tester to get after USA testers.

The hunts bridge is the early one the CRB. I have the CRB 3 (the sloping panel unit) and is constantly used, mainly as my Leakage tester. I have manuals for all if required.

it can test 1.4 volt series.

filament voltage to 10 volts

valve holder panel switch to 7 position

This is diffrent if the filament voltage extension box is used.

Nice one Steve, yes I forgot about the divide by 7 switch.
