6L6 are large tubes for an amp producing more watts. If you have the amp designed  for 6v6 voltages and bias settings you may want to wait for PRR or Sluckey to advise whether it is safe or if you will soon see smoke. LOL
You only fail ... if you quit trying.

This is great - I too have an A029 and FC Speaker.  Has anyone used one of these FC in any of their builds?

So - the 6L6's worked out well?

Excellent work, my friend! :nice1:

It's great that you did such a nice documentation.

Holy thread resurrection, Batman!

Well, due to some circumstances that have happened in my life, I did not have this amplifier for about 6 months. I just got it back last week and it had been sitting, doing nothing during all that time.

When I fired it up, I notice that the volume seems to be a bit down, meaning less volume than I remember. The 2 6L6's ought to be PLENTY loud, especially in the bedroom, but I really have to crank it in order to get some halfway decent volume out of it. I remember it being plenty loud at mid level volume settings, but now I have to dime everything to get it going.

Any ideas on what could have gone wrong?  All the tubes are glowing when I turn it on.



As an aside, it looks like Photobucket wants to charge me $400 per year in order to enable 3rd party hosting. I think that's complete bu11sh!t. Plus, their site seems to take FOREVER to load or do anything. Time for a change. Any suggestions?

Again, thanks to all who helped me on this amp. I really love it!

This forum supports attachments of reasonable size. There is a sticky post discussing image down-size techniques.

postimg.org and imgur.com are simple no-BS image hosts.

> what could have gone wrong?

Can't see it from here. Whoever is closest should be checking voltages.

Yes, I realize that a physical inspection would be best.
All I'm asking is for a point in the right direction.
I can check voltages, etc. I just don't know where to start, or what components would be the most likely of culprits.
