I'm sure you can find 6LB6's.
No problem finding them, it's the cost: $25.00 + for NOS.
I'd like to get some use out of them before dumping new $25 tubes in the trash. Just have to keep an eye on the set for the first few minutes after a cold start. There is a fuse in the HOT cathode circuit.
The CB'ers depleted supplies of color TV HOTs in the '70s building their "linear" amplifiers (and to a lesser extent, audiophiles. The amp in my avatar uses 16 European horiz. output tubes per channel) and drove prices thru the roof.
