What did your ears tell you Chief? I don't remember you saying the reverb sounded crap. ;)
All else is placebo.
This is a very dark thread.
Then again, perhaps "there is no salvation from the horror" is the appropriate response to someone called 'darkhosis'. ;)
The schematic is in post #6, not post #10
Here is the AC019-F schematic
No. The other side of the board the pots are connected to in your first post.
Did the acoustic that you tried have a volume control that you could turn down and everything was still fine?
I knew that bassline instantly from somewhere, can anybody help me out?
I'm with Just(r)in on this one. Blown bulb in a bass cab is like a memo from God. ;)
How loud is the spring noise you can hear from the return side? It needs to be loud. Or try with your thumb on the return cable.
Also, there is a great amount of loss in the tank, so not hearing...
Another thing to check would be if there is any DC from the amp input. Unplug the cord at the guitar and check at the cord for DC.
Ok, didn't notice that. That's why they have the second listing w/mod for more money. :(
I know the MOD brand tanks are very easy to change ground scheme, but have no experience with the new...
For some reason they are starting the number with 3 instead of 8. However, this 8CA3B1B tank description states it is for that model amplifier....
And that is called 'rigid loop' base, but I'm doubtful of those specs. Most of the bulbs in that package are 5 to 10W, 56W seems very high. In any case, there doesn't seem to be a generic version,...
If you know of an autoparts place with an old timer working there (other than the usual 'chimps' who will just ask for make & model :rolleyes:), show it to him and I bet he'll find you one.
Before I clicked on that video, I was going to say the fretboard looked like a freakshow to me, but I didn't want to be rude. Now I see they are embracing the term. :D
File just worked for me.
The schematic you linked has the reverb tank between IC2 and IC3, is that what you have there?
Have you inspected the clip itself? Often stuff that sits for a while gets bad corrosion on the clip contacts.
My thinking was that during normal operation, when a LED was on, drawing that kind of current, the supply should not overheat. 3.6mA at the secondary should not pull approx. 100mA from the primary,...
You mentioned re-doing chassis grounds, I've had weird issues similar to this where I had to clean the lug/chassis connection from the wire off the power tube cathodes. Cleaning up oxidization as...
Are you just going by ear, or measuring power output?
I agree with Pedro, the clean channel is going to sound quieter. It is possible that it's still not putting out full power as the difference...
I think you are correct about it being for DC heaters. One leg of the bridge is going to pins 4&5 of preamp tube.
Those resistors could have blown long ago, and I wouldn't necessarily expect them to be replaced with originals, so no big deal there. Bad tubes can take those resistors out. Or they may have just...
Doubt that the ptc is the issue, more likely the caps as were mentioned.
But where are you measuring the 3.6mA ? I don't see how that kind of draw would make the transformer get hot. That's like...
Where are you measuring? As far as I know, each power tube has a 4.7ohm cathode resistor. So you measure millivolts at the cathode and divide by 4.7 to figure out the cathode current.
Most likely the zener diode D108 was the failure. Zener's usually fail to low resistance, which is what you found. The excess current due to the zener failure would cause R306 to overheat, and the...
Look in the last pages for that schematic (post #21) for the later revisions. G is on page 16.
