The Hallicrafters SR-500 utilizes a pair of Tung-sol 8236s.

The 8236 seems to be identical to the 6DQ5, except for plate dissipation
(50W against 25W) thanks to the use of a carbon plate.

The 8236 seems to be available nowhere.

Any suggestion where to find them?

I think the 6DQ5 plate voltage is lower. Rare tube, they show on eBay
every so often. They were used in the Clegg Apollo as well. I looked
at a few suppliers I use and no luck.
