truly i just find the deville unusable in rehearsal. i play in a country outfit so distortion is not need to often. if i bring the deville to rehearsal my singer is asking to turn down when its on 2. granted the rehearsal space is pretty small.

1 thing i know i would like to do is reduce the power of the deville. i still want full power when needed but for the most part its just to much for a rehearsal situation. i would like to use both amps (deville/deluxe) in stereo at rehearsal. installing some kinda 30w/60w switch would be nice. any a...

rehearsal went pretty flawless. i think this case is closed.

thanks again for everyone's $0.02 i learned a lot.

repair made seems crackling is gone. take it to rehearsal tonite for a real test. thanks to everyone's $0.02. let y'all know how rehearsals go.

now on to the deville.

ok its been awhile but i found sometime to open this thing up. before i am to take out R57/58 i thought i check the specs of the ones on the board. on board: R57 measured 81.1K R58 didnt register on the meter new resistors: R57 measured 81.7k. R58 measured 99.7k with this info in hand i believe it i...

just order parts from MOUSER hopefully this fixes it. pretty cheap fix. will keep the forum update once parts are replaced. think my deville got same problem.

also while i'm doing this i'm going to replace R78/79 can i replace these w/ the 5w 330k or should i go back w/ the 5w 470k.

i took it to rehearsal last nite can't hear the crackling w/ the drums and bass and its the only place i can open the amp up at since i live in an apartment. did good for about 2hrs then it went a little haywire. loud crackling and static as described by http://www.justinholton.com/hotrod/plateloads...

++ on the PI plate resistors. While the circuit isn't identical, I saw these cause problems on a number of DeVilles back in my repair days. Replacing those, the switching FET and those large resistors fixed about 90% of the repairs on those models. the plate resistors are R78/79 correct? the switch...

Someone's earlier mod. Don't know what it is. i understand its a earlier mod more after what it is and what it does. The big, white "cement" resistors in this photos are the notorious ones that often fail in this amp. The circuit board is getting baked and is discoloring. They are part of the DC su...

ok before i was just poking around so i decided to take a systematic approach and follow the schematics. http://support.fender.com/schematics/guitar_amplifiers/Hot_Rod_Deluxe_schematic.pdf question #1 WTF is this http://dl.dropbox.com/u/32815923/010113161849.jpg and how do i fix it. question #2 is t...

i've read about R78/79 so i already took a chopstick and tried wiggling them around didn't hurt or help the situation. should these be replaced w/ the 5w 330k.

its a green board printed 1996. issue: turn it on/standby i can feel it slightly vibrating. take off standby still slight vibrating and there is a slight crakling. just put in new 6L6s havent change preamp yet. where should i look. i know how to dissipate caps. not scared to poke around a little bit...

i thought this is where it should go am i wrong?
