[QUOTE="Jazzy, post: 1123226, member: 2010"] A painful subject for me as well, I run 2x Svetlana sv572-10 output valves and have burnt through 6 of them since the pandemic started. As per Mars' technical explanation on pg.1 it turns out that Eskom's average voltage in our hood has crept towards 248v which I now know is the #1 reason for the short life. Plus I'm now home more with the music playing... Anyway luckily the Peter Souris Transformer I use as a power conditioner has a -20v tap, so going forward I will approach 1000hrs on the valves. But I have a similar problem, I don't have any spare valves and the cost to restock has doubled. Very bad if you have a valve type that doesn't have an equivalent from an alternative supplier.
