Hello!
I have seen several TV tubes, like for example PL509/519 marked as both. Can I assume that the tube can replace a PL519, which has higher power dissipation than the PL509? Are there any rules for tubes with dual markings?
I have seen both cases: "PL519/509" and "PL509/519".
Any insight is much appreciated!
Regards,
Jose

"Transistors have ratings, valves have guidelines." Well worth remembering. Never heard of HRS, so they were probably a rebadging concern who didn't actually make valves. That being the case, the only way to find out if their rebadged device will tolerate 519 ratings is to try it. And as I don't suppose for one moment that you're replacing the line scan on your television, you're outside the data sheet anyway...
I've seen dual marking on several replacement tubes like this one, they were sold as spare for repairs. Maybe this was a trick to increase sales: no need to check the tube replacement chart, and less concerns from inexperienced customers. They sometimes are a bit out of specs, some sellers were not picky about their suppliers.
A pl519 and a pl509 are inter-changable in my McAlister Audio PP-150. Peter McAlister, the manufacturer in Barrie, Ontario, Canada told me that I could mix and match these numbers. The PL519 is an updated version of the PL509 and was used in color TVs.
The El509/PL509/PL519 are all the same tube except for the filament voltage. The first number on your tube e.g., 40KG6 OR 6KG6 indicate the filament voltage. You cannot interchange filament voltage so if your tubes need 40 filament volts you cannot install 6 volt filament. The tube filament voltage does not affect the performance but of course your have to supply the correct voltage.
Just make sure on any of these European numbers that the filament is 40 volts.
Hope this helps.

According to the Philips data book (1975) Wa max PL509 = 40w and Wa max for the PL 519= 45w. Pg2 max for both tubes = 9w
