Carvin X Series 3

they make about 3 versions of this amp, 6L6, EL34, 60 Watt, 100 Watt, etc,

this is a 60 watt 6L6 model, first amp i have seen with plugs in the unused power tube locations,

output trans # OT-0600  EIA 606-142

EIA code sheet says 606 = Woodward - Schumacher,

here is a page with more EIA codes>

somebody stuck a speaker fuse in the cab, probably gonna rip that out,

speaker is a Madison Opus, 8 Ohm, never heard of that company,

Acutronics  reverb pan, 3.106.610

this must be the chassis,

hybrid type, solid state reverb drivers, channel switching logic chips,

somebody has been doing a bit of handy work, could be trouble,

pwr fuse just popped, gotta figure out why,

more trouble at the other end, kludge city,

I have a 1989 X100B on the bench right now.  Came in with 2 6l6's and bad sound.

www.carvinservice.com will be your friend.

First step for me is to trace out and validate the circuit.  Someone has been in the amp before and has put in some "mods." 

While this particular amp has the 30-x100-4b circuit board, it's not using the EL34tubes as noted in the schematic.

Looks like the only difference in the power section for 6l6 vs EL34 is the screen resistors. 

5W 350r for EL34
2W 470R for 6l6

Looks like that 2W part needs to be bumped up a bit.

pulling the pc board would be a big hassle,

ok this thing has a shorted OPT,

getting a chassis with a bad transformer is like throwing a steak to a hungry linebacker, 

here we go with the OPT,

they short stacked me with 7/8" on a 100 EI, s/b 1 inch for a sq stack to match the 1" tongue, WTF, over?

i'll eat a short stack of pancakes, but don't short me lams, jus sayin... ;D

afraid the bass might blow the twelve i guess,

opens up like a can of sardines,

coil/core assy>

laced with a Lap 1,

structure plain to see, pri-sec>

lead breakout, i bet org is the start,

working undercover, sloppy blk route, eh?

are they trolling for salmon with all the line hanging out? 

insl added to keep sharp hookup points from punching thru,

primary side>

sec finish which is the grn speaker lead,

inner wind is always the first to go,

water pump>
