I'd say don't turn the amp off, rather place it on standby. That will remove the high voltage and avoid over dissipation on the tubes remaining in the circuit, but keep the reservoir caps fully charged. If you switch main power off and on you risk damaging the rectifier. thats a good idea. thanks m...

Nice! A blast from the Hawaiian guitar past! Deoxit applied to the bushing and some gentle persuasion might free the volume pot. Working, but I'd bet replacing the electrolytics would really wake it up. some guys like steve kimock like those old shitty electolytics.. personally i like fresh ones bu...

hi.. ive got a trainwreck rocket 4 X el84's and wanted to swap el84's and see how the matching and unmatching and different brands mix effects the sound.. would it hurt anything to pull one el84 out while the amp is on and put in another one at a time in its place? some people say matching sounds be...

G'Day Mark 8) No reference to Merren making A470s, just that there are clones available as it's the preferred Rocket OT. Works great for a pair of EL34s too. It was OEM on Dynaco ST-70 amps. Those were pp pairs of EL34s running A470s as a HiFi amp. Maybe Chris has made these as well. Pacific has Ro...

the caps are polarized sonically.. so think of the stripe side as your + and the side with no marking as your -...
maybe their are exceptions but thats basically the "rule"... or another way to look at it.
and yes, dumble knew which way to put his caps

electroplex uses them in some of his amps.. they sound alright.. im sure theres no issue with "can't take it" as long as its 400v ... id use something else myself though.

the only tubes that can take it... the JJ 6v6s's
they sound ok, and the other options red plate...

yup those are the 84's... ive never seen those for sale.. and the ones they use for el34's and rectifiers are even cooler. they are shock mounted so isolated from chassis, then a metal clamp with leather or something like that inside the clamp touching the tube base. ive got an octal matchless and i...

like the super high quality el84 holders.. or the shock mount holders for el34 or rectifier tube types. the sockets themselves look like maybe beldon. but the holders ive never seen before and are really high quality. maybe they bought a million in 1988 and have had the same stock past 30 years? oth...

looking for original type boards for a rocket or liverpool.. anyone have some they are willing to part with or know if there are any options out there?
thanks!

kennys back up amp is a AC763.. bandmaster mod.. the hotel hog is a different name dumble gave instead of AC763? they are the same mod? . the rig sounds amazing whatever it is. the pedal is simple, basically analogman KOT

dumble AC763? never heard of that model... wonder whats going on there.
and landau's slidewinder head i think its safe to say is correct that its a tweed bassman like kennys. so i guess a big tweedle dee.
the rig sounds really good... pretty amazing

not sure PT is doing the ghosting .. but merren is the better PT in general.

yeah its a HRM.... if you really have the amp in hand... can't you just look at it? i remember it likeing a telefunkn 12ax7 in the first slot i think. is there something wrong with it?
