Accept's 200 watt JCM 800...
![]() ![]() Got this from HC. Here's Wolf's description of it: This is a Marshall amp that was built/modified for me by the German Amp tuner Baldringer. It is based on a JCM 800 model and totally custom made to my specifications. There is a tuned pre-amp section that has a Volume and a Distortion control. Then, instead of just the normal mono power amp section, it has a complete additional power amp section built in. So there is a total of 8 EL 34 tubes and two output transformers! It's a beast! Additionally there are send / return left / return right jacks with trim pots. Great for stereo effects. This baby is heavy (literally and figuratively) and has simply incredible power. I used it for one tour (Death Row) and performed flawlessly. I ran two Marshall cabinets on each side of the stage (for a total of four) with it. If you want to hear what it sounds like just check out the “Death Row” or “The Final Chapter” albums. If you ever thought of running a stereo guitar setup this is one serious amp! One word of caution, however. Since this a true stereo amp, you must connect at least one speaker on each side at all times.

Re: Accept's 200 watt JCM 800...
Does the power transformer look bigger? It doesn't to me. It should be a huge MO FO. Just the heaters in the power tubes would be drawing 12 amps. That amp would have to have a heavy duty power cord as well, because I feel this would be an amp capable of over 15 amps of current.
Now since a 200 watt amp is only 3dB louder than a 100 watt amp, it would seem that it would be more efficient to use two, 100 watt amps. This way, if you want to run in stereo, you have two independent tone controls instead of one shared tone control. If the amp is built with the proper components, there is no doubting that it would have massive headroom. I'm just saying two heads are as good as this one. (Did he have a spare?) It does however look cool.

Re: Accept's 200 watt JCM 800...
im 30 and i still respect and love all of the 80s metal bands, i hate to say it but alot of newer bands think they rock harder and have evolved metal but just because its louder sonically and pushed to the red doesnt means its more metal. some 80s music is just pure awesome theatrically, only few bands still possess this, like Opeth to name one.

And I don't think the intention was more volume, but more raw power. That's why I love 100watt amps, may not be much louder than a 50watt, but damn it's got kick. If Marshall made normal amps in 50/100/200, I'd probably get a 200watter. Edit: I guess the key to 80's metal is just to kick everything up a notch and really crank it to 11.

Re: Accept's 200 watt JCM 800...
I'm currently working on a new power transformer design. There's absolutely nothing like it on the market. It makes its own current.
Not to piss on the parade and tell you all that there's no Santa Clause, but there is no way in hell that power tranny can source the amount of current required to give a 200 watt output/100 watts stereo...not to mention a total of 12 amps heater current just for the power valves alone (75 watts of power being consumed by just the power valve heaters alone)...unless there's a 2nd PT that we don't know about. Adding an OT and 4 more valves drops the load impedance on the power supply to allow the load to draw that current from the PT, but if the PT ain't big enough to source it you're not gonna get it. Pushed hard enough it would sag the shit out of the power supply voltage, not to mention you can roast that PT quicker than shit trying to get that current though. Either way I call bullshit.

I'm thinking based on this statement -"it has a complete additional power amp section built in", there must be another OT on the left side we can not see. But how the hell did he get them stuffed in there???

No no, what they are talking about is the power transformer. The OP stated that there is in fact two output transformers. I believe what Wilder is trying to say is that the power transformer wouldn't be able to supply enough power for the amp to be what is stated.

Re: Accept's 200 watt JCM 800...
That's what I was saying earlier in this thread. There are a lot of things I don't understand like the shared tone controls for a stereo rig. You could run a left/right signal, which I believe is what they did. It's not true stereo.
The chassis is only so big and you are putting two OPT's on it, eight EL34's, 3 or 4 preamp tubes and supposedly one power transformer.Not a lot of room for anything else. Plus, looking at the power tube spacing, I don't think it meets the required amount of air spacing between tubes. If it does, it is close. I would have liked to see pictures of the full chassis and some other shots. Ritchie Blackmore, Billy Gibbons and EVH all were notorious for making up stories about their amps. I'd have to see more pictures of this amp.

Re: Accept's 200 watt JCM 800...
And when it came time to retube??? What then? Two matched quads of Winged=C='s would be expensive.

But this transformer wouldn't be able to supply the CURRENT needed for the amp to put out 200 watts of power. With two OTs and two quads of power valves the load would definitely try to draw that much current, but since it can't source it it would just pull the power supply voltage down and eventually fry the PT.

Re: Accept's 200 watt JCM 800...
That's something else I brought up to Jon. A pro player is going to have choice tubes. This guy should have like eight Mullard xf2's in there. Instead, it looks like a hodgepodge of tubes.

Just use a 1981 jcm 800 model 2000 250w lead amp.Saw them in early 80's in Guitar Center.I wanted two,just for fun.There is your power transformer t4312.Twelve point five amps,baby! Warm for the form!
