Can't go wrong with anything Guthrie Govan and Richie Kotzen got such great tones out of!

People who do things the right way will build their own regulated DC supplies to fit the amp, not retro fit whatever hack-job parts they have laying around their garbage dump of a bench space. Especially if they're charging for their services. I'd flip the fuck out if I paid a tech to work on an amp of mine and it came back with retro-fitted laptop parts.

"Temperature is of great concern to any capacitor. On a circuit board, capacitors should not be mounted close to heat sources. This applies to most capacitors, but especially to aluminum. A radiation shield between the cap and the hot component prevents the hot component from accelerating failure mechanisms, which can be simply a shorter lifespan..."londaxe":1kr1ogra said:FourT6and2":1kr1ogra said:No. No they are not.

Not sure if they were referring to the use of DC heaters in general or the use of laptop chargers, but the ones I've seen (while not many) have always been these little PCBs that mount to the inside wall of the chassis.

Never knew that. Guess I've got some work to do in one of my amps... I've got the axial type .68uf electrolytic (leads coming out of both ends) in a position in my 2203, but there isn't really any space between that and the resistor.

I've never actually taken a cathode resistor temp reading from a JMC, RK (or any other amp), but it would be an interesting process. If it doesn't get too hot, I would prefer them mounted on top vs. hassling with suspending them. I of-course wanted the RK to look cosmetically stock as possible... I made 3 minor changes which tweak the preamp bottom-end in my favor.londaxe":3qxbgyz2 said:FourT6and2":3qxbgyz2 said:No. No they are not.

Isn't that one of the things Mark is know for (using random parts)?
My Cameron amp had a crackpipe under the chassis...
Weird... It looks like Mark may have salvaged a voltage transformer (possibly from a telephone or laptop) and stuck in there to power the bulb in the lighted switch.londaxe":1qwdl2re said:charveldan":1qwdl2re said:

lol, you might be thinking of Fab Amps and the infamous street sign chassis. ha, now that I think about it, Dan would have been the perfect spokesperson for ol' Rob. Throw in the dude with the drum/speaker cab abomination and...man, don't even want to think about that. I don't think the industry would survive.
