That rig looks sweet! so each head has its own speaker?

SO you could run a stereo rig with that setup if you wanted? Like out of a stereo chorus or stereo delay pedal?

I thought most SS amps all use similar power transistors, i dont think amp builders use custom or rare power chips. Normally they dont just blow unless there is cooling problems or a shorted speaker or cable.

Ide hate to replace the OT transistors and then they blow again because a speaker is blown and shorted or a cable got bent or something and you just blow the new chips again.

I dont see why not, you might try an OD pedal and a Distortion pedal see which has the better sound. OD pedals like a tube screamer are meant to push the preamp tubes into saturation and give a more sort of distortion sound but the RX120 may benifit from doing it this way it also might like using a "Distortion pedal" something like a bad monkey.

NOt sure what type of distortion your wanting but there are some pedals that do both OD and distortion like the Boss and i think Marshall makes one.

I find the Clean channel is a very warm fat channel and when you run an OD pedal or a distortion pedal threw the clean channel it can get pretty thick. You may like that though

Dont be scared to try pedals threw your effects loop also you may get a sound you like running them threw the loop also.

I have a KH120 and the master controls the loop "Return" so you could also use your amp as a power amp and use pedals as your preamp, say a line 6 pod, or any pedals that are like a preamp like an OD or distortion pedal.

Amps that have a loop have so much flexability and having a master volume lets you control the volume from the front giving you so many more possibilities using an A/B switch so you could go threw the front or threw the loop

If you plug something into the line in or the return on the back do you get any sound?

There are 2 parts to a guitar amp, the preamp, and the power amp if you plug into the return with a signal like your phone or a drum machine and you get sound you know the power amp works.

Also have you tried the guitar into the front and a set of headphones what does that do?

Not sure about your amp but some amps when plugging something into the headphones cuts off the speaker outs. The headphone jack could need cleaned sometimes plugging something into the headphones then pulling it out quickly can fix the connection issue (if the amp cuts speaker out when using headphones) pulling the jack out quickly can fix it.

worth a try

Can you post the schematics? I have a KH120 i got cheap off craigslist because the input jack was broken (easy fix)

Ide like to roll the gain back on both OD channels, either remove the clipper diodes or change some resistance so the gain knobs have more headroom so to speak.

Is it true that all those amps are the same? Tone is same? Only some differencies in the layout and names? I am trying to find those ones so I need to know which one is the best for Dime tone=)
Hey guys,  So I got this Randall RG40 112SC from this dude on craigslist. It was super cheap.  35 bucks.  I figured the cabinet and speaker alone would be worth that.  I have a RG80 PH and I heard plenty of reviews on all other Randalls of that time era, so here is my dilemma. There is no footswitch first off.  Second, when I crank the gain there is zero , i mean zero distortion influence that is what these amps are famous for.  Clean all the way.  I am wondering if this thing needs the footswitch to operate correctly.  I almost wanted to guess that the amp was never meant to have the RG80 drive , but it has a gain, master, treble boost pull switch , i mean, it has to be a similar circuit in there. Any and all information you guys can provide for me would be awesome and thanks in advance.  Here is the manual of the amp I speak of btw.
Just picked up a second hand Warhead.  The previous owner reported that it would randomly lose either signal or sound (so I picked it up for a song).  Was kind of leery doing this as I picked up a RH150 a few years back with a similar issue and turned out the transformer was bad, discontinued and no retro fit was available so now its a boat anchor. 

Anyway it happened to me for the first time tonight, it'll be running fine and then totally kick out, you can hear the guitar faintly in the white noise a this time.  Then all of a sudden an earth shattering BOOM and it works again, did that to me a couple times and I stopped using it, because A) it just about torn my ears out B) I feared it might blow my 4x12.  Any idea of what might be causing this? 

Previous owner reported that he could get it working again by either messing with the volume or gain, or if that didn't work turn it off and back on again.  I also noticed the channel light will stay on in whatever channel you left off on when you power it off, I don't suspect this is normal?  You can actually switch the light one time with the foot switch from one channel to the other when powered off.

Any info would be appreciated!

Ok boys, one at a time, I can't keep up with all these replies.

Figured it may be the LDR (opto-coupler) then with my meter I realized there was no voltage going to it, now I suspect a bad transistor in the tremolo circuit.
