Guys, the 6C4 is really cheap, around $1.

As I said it is 1/2 of a 12AU7.

One of my objectives was to equal or reduce filament consumption since most of these radios are being run on power supplies. The 6J6 draws .45A. Five of these are gong to be rough on the rheostats.

I have run this conversion through every position and setting on the small box AK20 and it works very well. The only thing I have not tried is running 5 of them in the same radio. It may be a while before I make 5 of them.

I just completed adaptors for the UV and UX-199 as well as the UX-120. These use a different tube(s). To me, this adaptor is much more useful. Most UX tubes are not that hard to get but the UV tubes are becoming expensive - and I would not want to blow one up while testing a restoration.

I do not intend to make any of these to sell but I thought some of you might need some for the same reasons that I do.
