Well and I speak from personal experience, a 90W SS amp isn't loud and you may disappointed with it when it comes to volume. Now on the other hand for live use you don't need a lot of watts when you're mic'd up.

Well Gerry, heard this all before, the only amp that sounds like a tube amp is... a tube amp. The rest is marketing talk. I'm not saying that these are bad amps but a SS amp will never, ever react like a tube amp even with some preamp tubes in it.

Well this is what you get when you put an accountant at the wheel instead of a musician.

Send me an email and I'll send you the schematics back. The ones I have a very good readable.

Nice, let me know if I can help you out with anything?

The MT200 has a different power supply (switching) and doesn't come in a 240V version (at least I never saw one).

Well if there is one person that can give a good review it's you Chucky !!!!  >:D

ADA does have a 2 x 50W full tube rack amp called the T100S and it weights about 12kg in a 2U rack housing. Mine puts out around 75W per side.
But I can agree that an MT100 is not loud at all, especially compared to a tube amp. Sound wise they are not so bad at all IMO.

I do agree with Gerry that maybe that Koch amp won't be loud enough.

@R, a class D amp is NOT digital actually. There is no AD or DA converter in it. PWM is made when you compare the original signal with a triangle wave, this will output PWM signals which are then amplified by MosFet's (due to their low Rds on resistance) and at the output they just filter out the high frequency's with a low pass filter restoring the original signal. And due to the fact they can get an efficiency  of 90%+ they can use smaller (switching) power supplies and less cooling, so they are lighter then other power amps.

GREAT, they are not cheap but on the other hand will save a lot of time.So I'll order one from Thomann today.!!

Thanks SC.  :thumb-up:

Hey SC, do you happen to know if that intonation tool also works for floyd trems? that looks really nice, never saw something like that before.

Good guitar player

Hi and welcome!!

MP-2 / Re: mp2 comp on no sound

Well I already replaced all the parts surrounding the switching and nothing helped. My guess it's pcb thing, maybe it's conducting or something. Not sure.
Does the comp work after a while?

Anyone here have a manual for 'women' :???: :???:


Too long to upload   :thumb-up:

The engineer has know-how; the university-educated has know-why
Careful, when arguing against superior knowledge..

 ;D  Well did some work on this problem before, so I know where it is, don't have a solution yet.
