Re: My first telly TV22
Hi Helder just sent you a PM
Do you think there is any difference in performance between the later PY81 and the PL38 in your set. I had no problem sourcing a new in box PY81 (mullard) from a well known auction site for not much money. |

The PL81 also has a lower heater voltage and dissipates less power than the PL38. I don't know about reliability though. Many members here have stated that the PL38 is very reliable, and some even say they never had to change one. If your original PL81 behaves as well as the NOS one, I guess this reinforces the hypothesis that it is also a reliable valve. Helder |
