Nice. Is that SG a Gibson one or a copy? Why d'you like the peaveys and Gutierrez? (Apart from they look fucking great!). What is it about the cheaper ones that make those your go-to guitars except for the fact you care less if you bugger them up?
Not many of the guitar shops round here tend to...
I was watching that lil Fokker demo and the 'weird' guitar the bloke was playing and it got me thinking, what guitars do you folks like playing with your Diezels, which styles of music, which Diezel (or if you prefer that guitar with a different amp?!) and why? Obviously if you have hundreds...
Maybe a picture of a biplane Fokker would be more apt than the triplane, since it's 2 channels, but the Red Baron (one of the most legendary WWI pilots) flew a tri-plane like that.
Come on ke2! That's not a PROPER Lil' Fokker! This is a proper one, not that modern big thing...
:thumbsup:
I'm guessing the people who think it's juvenile only watch cheesy comedy films and don't know much about vintage aircraft!
Matt Belamy from Muse said he loves Diezel amps but didn't like the cabs at all in an interview I read once and used Marshall cabs! I love my Diezel cab and like it a lot more than my Marshall one. So I think it depends on personal taste, and although I'm not sure I'd agree with the "must get a...
I thought Hetfield had a Hagen now, or am I wrong?
tbh you can't go "wrong" with any of them. It's always best to try if you really want to be sure though. I'd very nearly bought a VH4, but when trying them in the shop I got a Herbie. If I'd got a VH4 though I certainly wouldn't complain, and...
That's a bit more worrying. That's nearer 8%.
I get my tubes from here http://www.watfordvalves.com/output_valves.asp which says they can match to 1%. "Can match to" and "are matched to" are two different things though. :aww:
I just made a long post explaining some of my reasoning but the browser locked up and ate it. :doh:
To cut along story short it's pretty densely packed in that power amp so I'd rather not add the resistors if I can help it. If it was a big empty box like most heads I'd be more tempted. I've...
So you think you should pointlessly modify an amp having resistors hanging off the end of a plate supply wire with an uninsulated part in a very enclosed space in the bottom of a rack mount power amp that get's vibrated a lot being transported around, just to save multiplying a number by 2...
De soldering 8 plates, soldering in 1 ohm resistors, biasing it, then taking them all out is "just making it more difficult". My proposed way is far easier. And I don't have to buy anything. I'm off to the pub to spend my bias adapter money on beer. See link above!
Ah ha, found this useful thing which answers the missing questions I had left and also agrees that my proposed method is valid, the easiest and cheapest, and one of the more accurate ones going. Don't need to buy any adapter or bugger about with resistors or soldering...
If there's a benefit to checking per tube then I guess those methods are better so I can know per tube (not that there's much I can do if they're poorly matched though).
If it's a 50W at least then I'd be measuring the plate current to a single tube and my method would have to be just as...
I reckon it's already done with my method unless you can see any reason it shouldn't work though. I'm not an amp expert but ohms law must still apply to DC in it? Why use a soldered in 1 ohm shunt resistor to each tube when I can use the output transformer (which is already there) as a 16 ohm...
Here we go! I made a video of me trying my theoretically correct biasing method. Should work for any vaguely similar amp with no test points if you don't have a bias adapter.
Still uploading but when it's done...

(Just the small question of which pot is bias and which is balance for the phase inverter. You can't tell from this side of the board. Let's wiggle 'em and see! Ah-ha, the outer ones!)
Cheers Steve! You posted while I was working out that above^
If I measure the DC resistance of half the output Tx'er with it off, then I can pairwise bias them using the 16Ω output transformer instead of a 1Ω resistor per tube. Should work since It's idling and DC so the AC impedance shouldn't...
Yeah, don't follow that plan of mine it's a load of bollocks!!! I want to measure the plate current, not the grid current. Twat! :doh:
I've managed to find a circuit diagram. There's no nice resistors to measure plate current across. The only thing I'd be able to isolate to measure current...
