Thanks for joining our little group.
If you have anything of interest to post, please do. We all can benefit.
I for one, was unaware that supplier had merged with the "big guys".
You will need to add a series resistor to the diodes, as the B+ will go up a lot, and don't forget to take into account the higher line voltages we have now days too.
I would suggest you mount the diodes (Please read my blurb in the forum about diode lead length) and resistor to a 4 pin tube socket for ease of changing back. You will need to likely recalibrate the tester after the mod too.

lamp is available from O'reillys auto parts, at least that is where I got mine. Buy them by the box, as they are really cheaper that way. IIRC, I got a box for less than the cost of 2 in the bubble packaging. This was about 10 yrs back though.
Personally, I would really try to find an 83 tube. The tester I had that had been previously modified by the other owner, really didn't like the diode mod. It didn't really want to work very well. I might have an 83 around, but no idea where in the tube trailer I put it. (Ask Cliff- he has seen it!)

But who knows what else the guy screwed up.
