Nic,

May I know if I can tube roll 5Y3 on Appollo's power supply with 5R4GYB or U50?

Thanks

You may used both 5r4gyb or u50 as a subsitute.
You can even use gz34 too

thanks
Nicholas

In that case, it means I can also use 80 tubes with the 4 - 8 pin adapter, am I right? Please confirm.

80 is one of my favorite rectifier.

I really want to know if I can use 80 rectifier, with the 4 pins to 8 pins adapter.

Sorry i took a while to test out whether this can work in our unit. Did a mod by replacing the 8pin socket for a 4 pin socket. Did not have an adapter, but its the same thing

If you use a 4pin to 8pin adapter the power supply can actually take the type 80. WOuld not be a problem.
