Hi, for the price it may be useful. Beware the paper index (on the rollers) tends to get bunged up and become useless. Like all similar tube testers if it indicates a bad tube...it probably is. If it says good then you really can's be sure. Such units are good for matching tubes though. A close match on the meter usually indicates a close match of performance.

Good listening
Bruce

Hi, It is hard to tell until you look at it closely. It all depends on how well the original builder made it.

Good listening
Bruce

Hi Alex. It looks pretty clean. There may not be much to restore other than a surface cleaning. No capacitors to replace as the lone orange drop cap should be fine. From the photo the wiring looks clean at that may be all you have to look at real closely. I've got 3 testers now and pretty much the only things I have done to them are cosmetic and power cord upgrades. Also be sure to look over the power cord well as they tend to crack if dried out and from sun light.

Just beware that the Achilles heal of most of these old tube checkers is the power transformer. Sometimes they are good to go, sometimes they have some bad windings, sometimes they just let the magic smoke all come out.

It is possible to make a replacement with the Tinker Box transformers that Edcor sells (like this HV one and this filament one) but some custom design work may be required.

Good luck with your new toy. :D
