RE: Replacement of 5Z4P tube

Posted by pc123v on June 5, 2014 at 10:44:06:
Hi Eli,

Is there a difference between the Shuguang 5Z4P and 5Z4PA? Got Sovteks 5AR4 to replace the Shuguangs 5Z4PA (I am using 2 5Z4PA in each monoblock)but am going back to the Shuguangs as I don't really care for the Sovteks.

Of the 4 5Z4PA that I have...one has gone bad. Am wondering now if i can replace the 5Z4PA that has gone bad with a 5Z4P.

Thank you in advance for any advice you can give.
