Graeme Parfett wrote Sorry Nick,

The numbers on the 4 diamond shaped silver thingies with the black fins around them ?

as can be seen here (big pic) numbers are:

2x MJ3001 TB3849 or T83849 not sure
2x MJ2501 TB401 or T8401 not sure

Not bad transistors. Used by B&O quite a lot. The reason I asked is that transistors are not as hardy as valves, so your chances of smoking them are greater. Luckily they available in SA for around R40 a pop.

good to know ? doubt I'll smoke them. if theyve survived since mid 80s (if theyre even original) ?

FenderBender

An iffy speaker cable can smoke em for you and this often happens when gigging and using someone else's cables :'(

my power switch doesnt light up, is it possible to replace the bulb inside it? or must I replace the switch. if so, is it a generic item? ???

Spoken like a true tech... ? I often wonder what Joe Public must think of us 'geeks'.

Nick, thanks for the shots, always nice to see the innards of goodies.

The power switch/light are single unit, you can't replace the 'globe', since it doesn't seem to have any wires going to it from the PCB I'm going to assume that it is a NEON, you should be bale to get a replacement for it fairly easily. Communica would be a good place to start.

That funny multiplug and cord look to be USA plugs, that and the USA on the inside of the map make me think that the amp actually runs at 110-15VAC, the multiplug prob has a step down transformer in it.

Cheers

thanks, will buzz past communica tommorow and see if they have ?

Awesome didn't know about them, thanks.

Found this shielding product on their website that could be possibly be used to shield the cavaties inside a guitar:

Is this similar to conductive paint?

Sorry for the thread hijack.

Yip, similar. Just to to check it is electrically conductive not just thermal conductive!

Since it looks like both of you guys are popping into the mic shoot out on Saturday at the studio we can pop in there if you want? Communica's Cape Town office is 2 mins from the studio, maybe meet up there before 12pm? You guys will love it!

Cheers

mine has 6 pins on the back though.. hrm

Then I can only assume it is a DPDT (Double Pull Double Throw) switch, indicating that the power switch switches BOTH of the primary windings. So all you have to do is ask Communica if they have a DPDT rocket switch in that size with NEON indicator.

Either that or 2 of those 6 pins are the lamp/LED, are there any wires coming from the circuit board to the switch itself? Are all 6 pins being used on your switch?

Cheers

Matt

nick

so the switch doesnt have 6 pins it has 5. strangely the black wire comes off the same place on the transformer as the brown wire but..

has this black heatshrink piece which Im assuming is a resistor of sorts to maybe drop the current for the old incandescent bulb in the switch? all new switches are 4 pole so Im guessing I leave that one off?

FenderBender

I'd agree with you on that one. You can't do any damage leaving it off anyway so give it a try.

nick

off to communica in a bit to source a switch then off to matts studio for the mike shootout ?

nick

so I get a switch from communica after writing all the details and even measuring it. get home solder off the wires solder them on the new switch aannnddd it doesnt fit. ☹ switch is too big for the cutout in the amp ☹ soldered the old one back in.

nick

I attacked the other switch with a stanley knife and if you cut off the ramps it fits fairly snugly but you got to remove all of them. soldered it up and the lights on ? all the time ☹

now its a 4 pole rocker switch, it connects top to bottom on either side so the only thing I could've got wrong is the wires on the wrong sides? either way Im going to get another one and cut it neater, this one was just a test. for now I leave the power cable out the amp when its not in use ? does look nice having the power light back though.

edit: and as you said matta, the neon in it doesnt affect the amp. no buzzing etc ?

nick

after spending entirely too much time on a stupid switch its working ? goes off when its off now ?

Lekke dude! How does that thing sound? You like it?

Fritz Brand wrote Lekke dude! How does that thing sound? You like it?

I enjoy it, I personally dont think it sounds like the valvestate marshalls, clean channel is nice and mid punchy, overdrive is strange, it gets dirtier with more gain but then when it hits 8, 8-9 is like 1-7 if that makes sense this huge jump. has nice reverb and I prefer the marshall way of two channels with volume and then an overall volume. so yeh Im happy ?

will probably just aquire a marshall footswitch for it, its got the original one but if I ever one day gig, no ways Im taking that thing on stage and breaking it.

FatBoy

Cool man, yea that footswitch doesn't look like it will be able to take much abuse. Glad you are happy ?
