Dude, you have the patience of Job to sit and drill all that out by hand!!
I did one or two like that years ago-never again!
Looks great!

6L6s generally operate in the 40-50ma range, correct?heisthl wrote:Power = E x I or P = (R X I) x I so if your tube was running at anything less than 223ma you would have (1 x 223ma) x 223ma or .49watts.

I've been jonesin' to build something ever since I registered in '06, and any way I could cut price (obviously I consider my labor as being worth nothingFunkalicousgroove wrote:Dude, you have the patience of Job to sit and drill all that out by hand!!

I'll be the first to admit that this is one of the dumbest projects for a first build, and even dumber to scratch build it, but I figure if I can get this to come out I'll be ready for anything.
In any case, thanks for the kind words.

I'm not looking at a tube manual but IIRC max at full signal is around 150ma per tube before meltdown.benoit wrote:6L6s generally operate in the 40-50ma range, correct?heisthl wrote:Power = E x I or P = (R X I) x I so if your tube was running at anything less than 223ma you would have (1 x 223ma) x 223ma or .49watts.

So you're saying I can't melt the resistors without blowing the tubes first??

As heisthl has shown, at idle the current is not that high. I wonder about the peaks and valleys of voltage and current during operation with an AC signal (just asking, I don't know).
I guess we should ask heisthl how big of a resistor he uses on his amps
For me, I'm a 'monkey-see-monkey-do' type so I'll be using 5W.

Heisthl is the MAN
So... I thought my chassis was just too thick for faceplates. Good thing for me, I was completely WRONG! Heisthl took my visio drawings (which I figured were just wishful thinking) and printed some fantastic looking stick-on faceplates. I've been busy lately so I just got them attached. It was a pain because I'd already installed the XLR footswitch jack, which mounts to the outside - I had to completely desolder
It's all done now, and the thing looks pretty ok!
So thanks a bunch Heisthl.. without further ado, the pictures:

Fine looking amp - where do you get the XLR connector on the back - is it a switchcraft?

I believe I got it from mouser, and yes, it is.bluesfendermanblues wrote:Fine looking amp - where do you get the XLR connector on the back - is it a switchcraft?

Nice looking build!
Very cool of Heisthl to hook you up with the faceplates. They look great.

Re: Heisthl is the MAN
Looks great, but why would you call the level control ratio? It is level since it is also a master. Ratio was a non HRM term.
Unless this is now a non HRM...
It would bother my obsessive compulsive psychosis.... LOL

face Plates
Is there a tutorial or thread on how yo print out thoes Great looking face plates? I'd like to make them my self instead of going to Kinkos.

Not that I know of. Heisthl's the man to ask.toneman wrote:Is there a tutorial or thread on how yo print out thoes Great looking face plates? I'd like to make them my self instead of going to Kinkos.
