Steve - Sorry, I was just making a comment about the dual bias set-up. Don't see that very often.
d95err - I think that 'noise gate' deal...

"...the preamp tube heater (12AX7) got very bright--and burned out..."
Here's my question - If, according to tube specs....

Here's my opinion - typically, a 5Y3 is a 125mA tube, so I'd use that number as a guesstimate.

Not an expert at all - typically, the transformers with the highest primary inductance are 'better' due to better low frequency response.
Inductance...

My old '62 Princeton has been running without screen resistors for a long time, with no ill effects
MY RCA19 book states that using a power...

d95err - I had read somewhere, that the -3dB point on a cathode follower (bypassed) should be 1/10th, but never actually thought about why. Looks like you...

The thing about MOV's is that they degrade every time they take a 'hit'.
If you're nned spike protection, you can use a cap.

Here's a simulation of that particular filter (AC Sweep) - http://home.texoma.net/~flhh/ga10t.jpg

Just my personal perspective, but if some amp is in "the shop", it's most likely got some problem. Potentially, a problem that could cause the...

I'd say that's a correct assumption! You could add an L-Pad to eat up some of the power, and keep the cab safe.
You can do the math yourself,...

Hey Alf, glad that was of some benefit.

Hey Alf, Load Lines aren't as complicated as it may appear. The only thing you need to know first, is the plate load resistor value and your B+. Then you...Last edited by Earl; 04-08-2008, 04:46 PM.

Alf, the easiest way to get these numbers is to use the plate curves of the tube, and a load line. You can get all the data using this method.

Essentially, if you can get the output tube Vgk to 0V via the PI plate signal(s), then the amp is maxed out.
If this is true in your design...

As well, the gain number really only holds true at some reference frequency. If you do some cyferin' with a Champ BASS/TREB passive EQ, you can get a 1st...

More than likely, you just can't tell...unless you measure it. And *if* you use the strict definition of "A", with a 360 degree full power plate...

Narrow Panel Deluxe question
...what most refer to as the 5E3.
Just from looking at the schematic, and it's similarities with the Champ (aside from the twin 6V6's), I had...

Yeah, I was refering to the other things going on in that particular amp. Passive EQ's are .....well......passive EQ's .. :-)
I agree about...

"odd", because I've never seen an amp wired that way. For instance, the unusual bass level control, and the way they voltage diviede one of the...
