Metroamp JCM800 2203 Kit for sale , More Info!!!

[onedrum]

i think i know what i'm gonna be spending my pennies on this spring... this may sound like a dumb question, but are there mv's on these? if not, would it be easy to put one in?

[stump]

This is a master volume amp.

thanks stump! anyone know if these kits be pcb? sorry if i'm asking silly or annoying questions, i'm just excited about it!

I believe the ckt. boards (assembled and kits) are already available. You can get them with the pcb-type mounting.
I assume these are what will be used, I could be wrong...

I'm most excited about this:

Doing lots of work on the 2203 stuff today. I'm getting pretty excited. *** I got samples of the brushed, anodized aluminum too. We had to make it from scratch. Looks great! ***

no, these will be ptp like all the other amps from george. no pcb (printed circuit board), just ptp-boards... but i assume you meant that anyway.

[onedrum]

awesome!! i thought the originals were pcb so i just wondered if that's how they were comin.. glad they aren't. i'm fairly hard on my gear and it'll be nice to know everything's not pcb mounted. i gig/tour regularly etc so yeah. y'all know what i mean. haven't had too many issues with pcb on my split channel 800, but i've seen issues with other amps, and my other guitarists amp, so i'll be safer this way.

marshall started using pcb's in mid '72. a friend of mine wants to sell his '73 superlead, and i'm thinkin about gettin this one, it's completely stock and in awesome condition... i only need to talk about the price. haha...

tonewise it wouldn't make a difference, but i find ptp boards to be more servicefriendly, better to tweak, and it just looks better. so if there's a problem with an amp, i wouldn't bet that it is the pcb that failed, it's more likely that a component, a resistor, a cap, or whatever failed... but this could happen to any amp, no matter if ptp or pcb.

[stump]

Not to get off topic but a good PCB design will yield the same tonal results and reliability as its turret board or point to point counter part. I know that this is debatable to many so this is my personal opinion. As an example just open up a THD amplifier. The PC board is incredible. Thick, with no noticeable flex and the traces would require a Dremel tool to cut. There are other builders that make great PCB's too. Marshall boards aren't the best, but certainly not the worst. I've worked on the board in my 4104 without any trouble. I definitely wouldn't need a Dremel to cut the traces though.

like i said before:

"tonewise it wouldn't make a difference, but i find ptp boards to be more servicefriendly, better to tweak, and it just looks better."

another huge advantage of a ptp board is that it is more cost effective than a one-off pcb board.

i understand that most major companies are using pcb's in their amps, cause thousands of printed boards that are machine assembled are a lot cheaper to do than ptp boards that are assembled by a lot of employes, and thats also why i don't really care if a 73 superlead or whatever has a pcb inside and i want to keep it the way it is.

on the other hand, if i build an amp on my own, i'd definitely go ptp, even if i can have pcb's for free, because you can tweak your amp the way you want, you can add or remove components easily... if you want to change components on a pcb you mostly have to take it outside the amp of at least have to lift it so that you can solder/unsolder the desired components. you don't have that problem if you go ptp. i had 2 blown resistors in my 6100, and i had to unwire the power tube sockets, removing the nuts from the outputs and a couple other things... that wasn't big fun at all. at least i hope that nothing ever happens to this amp again. changing 2 resistors in a handwired amp takes about 10 minutes with cigarette break.

and beside the fact that the early marshalls had ptp boards, i guess these are the most common reasons why most builder here are goin ptp.

[VelvetGeorge]

Exactly right guys, they will be PTP. Primarily for the tweakability factor. But also because that follows the Metro product motif.

Hey George,
Would it be possible for you to put up more options for us to when we order on the kits? Like I want PEC pots instead of the CTS that come with the kit also the low voltage tranny and things like different caps (IC MPW's), resistors and parts like the trim ring that go around the power switches. Would it be possible to do this?
If that is to much to ask I totally understand!

I'd like to be able to get 25K linear and 250K Linear PEC pots for the treble, mid, and presence. Are you guys screwing a nut on the PEC pots before you install them? That way the shaft doesn't stick out as much.

And this will be cut for rocker switches. I don't think those use any kind of trim rings.

And, it would be nice for those of us that are going to have the SDM loop installed, if we could get the rear panel cut for it to match the holes already drilled in the chassis.

yes, there's a nut on the inside of the pots in my amp... but that's with the plexi panel, i don't know if the metal panels will have the same thickness.

the rocker switches are usually snap-in type, no need for trim rings if the cutouts are right.

and you could place the rearplate in place WITHOUT stickin it to the chassis, put the fuse holders and/or jacks in so that it's fixed, mark from the inside where the loop jacks will be and drill them by yourself. shouldnt be that big problem.

Dude! Appreciate that an amp kit like this is going to be available!
The holes will be in the chassis, it's a simple matter to drill out the holes that you need.

I agree, it's a great amp kit.
