valves dont sound so good when pink....

adamus · 2nd October 2009, 09:12 AM

Just had another genelax reissue N709 (EL84) go.

I was happily listening, heard some distortion and then over a period of three seconds the valve went pink then started arcing badly.

Luckily it hasnt taken anything with it which i am fairly amazed at, it was quite violent.

out of my original batch of 4, i have lost lost 2. I wonder if its coincidence, or i have just been unlucky with a bad batch.

I have used tyhem for around 7 months. I assume there would be no chance of asking the retailor for a replacement?

Doch, try asking him. Depends how good a customer one is. Are you inserting them in/out of the holders straight and cleanly without wiggle ? (this is important)

Hi,

Seems every manufacturer over the last couple of years has had a bum batch of valves too.

Maybe switch brands for a couple months?

Cheers!
