There are a lot of these tubes out there. I don´t mean the picture tube, but all the other ones. F. ex. the well known audio tubes 6CG7, 12BH7 and 6CW7 etc. are actually designated for TV-sets.
There are a lot of other quality tubes in Europe & US, costing almost nothing, like PL84, ECF82, PC86, PF86 ECF83, PL81 etc (P stands for 300mA heater current & E for 6,3V voltage)
F.ex. the EC/PC86 triode will outperform ther popular ECC88/6922 types with lower noise and higher gain & linearity.
In US there are 450 & 600mA heater current tubes I think.....(due to 115V mains & series connected heaters)
When a manufacturer sold a tv-set with 20-30 tubes and guarantee, the incorparated tubes have to be of very high quality.
If you have made an amp or other things with these tubes, please give a hint or schematic diagram in this thread.
