Yeah definitely could be the probe. Sounds like all is good though which is the important thing.
I always really liked the JJ circuit, the BE channel on it with the JBE off is a blast. I found myself wishing it had a touch more gain that way though so I built one with added HBE channel and the full Deluxe-style NFB controls. It's one of my most played amps.
Dave is awesome, literally one of the most helpful guys I have ever dealt with.
How's the reliability of those amplifiers? I see a bunch of no-noes in there.
I've owned 3 with no problems and haven't seen a lot of problems across multiple online groups.
I'm curious to hear what you consider "no-noes"
The reason I am asking is not to bash on the amp/maker. I am just wondering which of the theoretical problems are actually non-issue on an amp in normal use. Given the responses I've got, it looks like all's fine.
What I consider a no-no (it all comes down to vibration):
* radial electrolytic caps used in place of axials: if there's vibration, the base doesn't work as support against lateral loads - it's just the leads that take up the load. The caps weren't designed to handle it.
* the radial film caps - the same problem as above and on top of it if the lead is bent right next to the body of a cap the resin can crack - moisture might creep in over time which would lead to capacity drift and dc leakage
* components supported by one lead, the other end hanging in free air, soldered to a wire
* components, especially relatively heavy film caps hanging on very long leads
* sharp bends on single core wires
Awesome, thanks!In all seriousness none of those are anything I would actually worry about (nor have I seen anybody else concerned). What I'd consider the final word is Cantrell and Steve Stevens have been touring with these amps for years with zero issues.
Components do (I should have used the word "leads" instead of wires).Also wiring is stranded not solid core so definitely not an issue. Generally anyone that isn't clueless will not use solid core wire in amps because it can get breaks in it way too easily.
Yeah, in military if things fail, people die, often a lot of them. While a guitar amp is a different story. The conditions the equipment is used in is different too... Both the engineering and market prices reflect it.To be fair I have never see a turret or hybrid amp that was built following actual mil-spec construction and solderinng... everybody does their leads "wrong" for strain relief etc etc etc

I think on Five Watt World i thought i heard that Ken Fisher on his Trainwreck amps used solid core wiring...i wonder what his reasoning was , yes, it will stay where ya lay it and maybe looks cleaner to some ...but stranded is more pliable and most likely be more durable being the industry standard
