There are no diodes in the signal path in any of the MTS-modules. Diodes are typically used for signal clipping in overdrive/distortion pedals, where the differences in forward voltages in LEDs and regular diodes affects the clipping. Some amps use diodes for clipping as well, but none of the...

I see. Sorry, I misread your problem. So it seems your problem is that the signal is shorted to grund when you put the ground lift in the [normal] position. First of all I would make sure that?s what really happens. If you have some sort of meter you should set it to the "beep-function"...

Well, are your RM4 and RT2/50 physically connected with anything but the cable? The reason for a ground lift is that usually rack units will share their ground by having their chassis mounted in the same rack. The ground lift.. well - it lifts the ground in the signal path, and if there is no...

Thank you! That one will do just fine :)

Feel free to post that one as well :)

Nobody with a gut shot to share? :cry:

I have two blackface modules, and I thought I might as well convert one of them to a Deluxe. Anyone got any close up gut shots to share? I don?t trust the PCB-layouts to be 100% accurate.

Just found this cool thread. I?ve been thinking about upgrading the coupling caps in my amps lately, and any upgrades or mods I could do while I?m at it would be very welcome.

Acually, I believe that the Decimtator should be able to handle the line level signal. I?ve always had mine before the amp, so I don?t have any first hand experience. But it is mentioned in the Decimetor manual that it can run in the effect loop. I might be able to test mine in the loop later...

What kind of effects are you running in your loops? Most effect pedals are not able to handle the relatively large signal (compared to a guitar pick up) output from the preamp. This will cause the inputs of the effects to overload and will (in most cases) create a less pleasant sound.

Seems to me the fried trace is the one leading from the plate of V3 to the output transformer (the brown lead seated on the connector in the pic). I?m not sure what might have caused this, but i guess a shorted tube might be guilty. Another possibility is that there might have been a tiny...

You are off course absoloutly right :)

Well the c14 cap mainly will influence the mids. In more of a mid- an high gain cicuit it would change the gain structure quite a bit, but however in a clean module like this it won?t affect anything but the overall eq. You are right about the modules sounding a bit different, but to my ears...

Well, I have a KH-1 and a Blackface sitting on my desk right now, so here?s the answer: After looking at these modules component by component, I can find only ONE component that makes the KH-1 into a KH-1 innstead of a Blackface (except of course from the chickenheads and black faceplate :wink...

Thank you, Smokey and Soulinsane. The Hunter: Yes, it's true that V1 is a common tube for all the channels. It's probably used for the first and the last amp-stage. Some say that the first tube-stage is the single tube that will have the most impact on tone. So, if you're gonna buy just one...
