Hello all, stoked this forum exists !!! This is my 1st post, I have just joined.

This amp (the 5E3) is my very 1st tube amp so forgive me if I am a little bit of a newbie.

I lent this amp to a mate at work (he's very knowledgeable with tube amps) and he said he loved it,
as did my brother-in-law, I love it as well, its awesome, I think I'll have it in another 5 decades.

Anyway, I was interested in playing around with different brand tubes and seeing what kind of sounds
I can get out of this amp, my question thou, and I did read it elsewhere but I just wanted confirmation
from you guys, if I change different brand 6v6GT's do I need to bias the amp or not ?

Cheers, and thanks for your time, Adam

Hi there,
The 5E3 is cathode-biased, no need to worry about that. Check out Fuzzy's post and replies. This amp runs HOT.
I had a PT prob right out the gate with mine and I thought I changed the recto with the PT, but it's a dead ringer for a brown base Sylvania 5Y3GWT. I'm not sure what Nik uses but this is not a Sovtek. Point being, check that rectifier tube. If it's that brown base, no labeling just 5Y3GWT stamped on top, it's a goodun and built like a tank. If not, go NOS on your 5Y3 ($30-40 maybe less), it'll run cooler and probally last a lifetime.
On power tubes, I highly recommend the Tungsol new issues. They're heavy duty, run cooler and sound great. They are a little more expensive but, IMO, worth it.
I hope this helps a little. You could go Ga-Ga on the NOS thing and well worth investigating but I think this will give you a great start.

I installed a larger value bias resistor in my clone. Just seemed like it was biased way too hot with the stock 250 ohm resistor.
Good Luck

You should be okay trying different 6V6's as long as everything is in spec.  The B+ voltage should be around 375VDC, and not much higher.

Never use a modern 5Y3 rectifier, it'll raise the B+ higher than most 6V6's like to see.  Always go NOS, NOS 5Y3's are $10-15, same price as modern ones and one may last you a lifetime.  This point should be moot, because, IIRC, Ceriatone ships with NOS 5Y3's anyway.
