Who needs pyrotechnics when you have exploding amps!dlloyd said:The first run of Trident, Bonneville and Speed Twin guitar valve amps were prone to spontaneous combustion due to badly laid out pcbs..

Microbass said:TE was bought by Gibson in 99 (i think) - could be as early as 97 tho!I thought the date was somewhere in this thread...
Now, my problem.
I need help.
My Trace still isn't fixed after having numerous checks by the techs. They keep finding dry joints they had missed.
They thought it was fixed, when I tried it out, infront of the tech it made a slight popping sound and started too feedback and some smoke came out - they fixed this and it turned out to be a really bad joint in the pre-gain stage.
I'm beginning to think.. screw having to wait a week just have a dry joint repaired - i can do this!
basically my problem is this: i get a really low output, but AMAZINGGGGGGGGGG tone.
it's barely loud enough to practise, and definatly not loud enough for a gig.
i'm going to have a look inside and see if I can spot more dry joints. however, my question is this: is there something else the techs have missed? is my power dead dead and just going to keep my output low?
i can have this "repaired" for free atm, so is there something i could ask the techs to look at specifically?
Luckily I won't be gigging till Sept... but I don't feel like waiting..
another thing ive noticed is that when the amp is muted, its louder that it used to be. is there a possible grounding problem when the amp is on and thats where im loosing volume?

Not too far off. My AH600SMX is dated 1991. Series 6 was in the years preceding.dlloyd said:I think the series 6 was early 90s and SMX was mid 90s.

niftydog said:ok, late new-comer to this thread, but now you've got my ears pricked up.
I too am looking for rack ears, but for a GP12SMX pre with a model 4001 (I think) power amp attached.
Any info appreciated!

tombowlus said:Interestingly, there are holes cut out for two more power tubes, and the manual states that except for the two additional power tubes, the Quatra and the Hexa are identical. If this is really true, then I've got some ideas brewing...![]()

oddio said:Tom, you may want to look over the schematics. I seem to recall that the Hexa used larger transformers.
oddio said:Perhaps PBG will chime in... or you could check with Shane the next time you chat with him.
