Have you checked the 4 HT fuses at the back? The first batch of RM100s shipped with 250mA fuses, but eventually Randall said they're safe with 400mA fuses. If you've got a bad tube, the HT fuse of that particular tube will blow. In my case, it as very different. The power amp is completely...

I've also experienced that too... the E34Ls, the EL34s; THE FAILURE RATE IS HUGE. I don't know with KT77s but I think I'll give the new Tung Sol EL34Bs a run for my money.

Necrobumping... My amp is blown (again) but I haven't seen the guts yet. All I know is one of my JJ EL34s literally shattered and the plates are exposed now. :roll:

Why don't the Recto/Rectified/Treadplate modules have that famed "Mesa sag" that makes your leads sound so liquidy and loose?

That's what my tech tried to resolve- by putting two jumper wires as a "flyover" for the grounds. The cutesie electrons would prefer to pass there than jump over air.

one major complaint that my beloved tech said that the PCB layout in itself was sacrilege! Maybe Randall wanted those spade connectors from the OT wires to be installed quickly without having two or more separate PCBs. the only separate board I saw was the MIDI board. But putting a high...

Check out what my amptech did to my RM100: He used a cutter to destroy the PCB track between the ground and 1ohm bleed resistor (Check the grey resistor at V4A), and installed a jumper instead. Apparently, the 1ohm resistor is the first line of defense to avoid arcing, which works sort of...

Remember I posted a thread asking for help on my dead RM100. To make a long story short, I kept blowing HT fuses (used to be 250mA and replaced them with 315mA), and eventually, two 1.6A internal fuses blew. Replaced the two 1.6A fuses with 2.0A ones, and then, my amp had a spark. The pic...

Special Thanks to okstrat for the invaluable info on the fuse location thread at the Gigmod forum. Anyway, here's a pic from that forum: I checked out the internal fuses and turns out Fuse 4 and 5 were busted. They both are 1.6A in rating. The local electronics shop had no 1.6A fuses...

I just installed new RUBY EL34BHTs and biased each tube for 37mVDC. It was working and suddenly, I heard a small 'pop' sound. Then, no sound at all. I replaced two of the HT fuses, which blew. But even after, there is no sound as yet. :cry: What is wrong??? Don't tell me it's my OT.

What is the problem with the amp? I already changed them to 310mA fuses to avoid the common problem with blowing HT fuses. My tubes are less than a year old and used primarily for studio work although I crank the amp to 5-7 most of the time. What causes this? Changed the fuses now and it is...

I currently have an SL+ module for my RM100. At the least I'd say it sounds like a Plexi on steroids, however, it has this annoying glassiness when the gain kicks in. I've pondered on modding it with the JCM800 voicing mod, but then, I also thought getting an SL2 can be a better idea. How...

So are you saying that it is impossible to redesign the RM100's 3-button footswitch so you can have mode 1A, 1B and 1C, 2A, 2B and 2C, and 3A, 3B and 3C? My thoughts on "the octopus" (ok, the name is not yet final) is that you are essentially having 3 different modes per slot. Not...

Would you like an MTS slot octopus? Something like a slot multiplier per channel. Say you have an RM20, if you use "the octopus", you can have up to 6 independent channels, mainly channel 1 (x 3), and channel 2 (x 3). gonna use the MIDI thrus to turn on each channel independently. I wanna...

Thanks for the advice. Nope, I haven't changed the fuses yet because I am too stupid to find out that each tube had its own fuse. :oops: Anyway, by any chance, are the stock fuses in RM100s underrated?

... and tried switching perfectly-working tubes, and the Tube failure LED's won't go off. I mean, =C= EL34s out from the box. I noticed that the sound coming from the amp is not bad, but not "in tip-top" condition though. The order of power tubes in the amp are as follows: outermost...

I also thought of another thing that is quite a Gray area regarding this matter - The Clone module kit... best for DIYers with Egnater and Randall MTS amps. You do the soldering. The board is ready, and all you have to do is assemble it. But that means, the purchaser of the kit assumes FULL...

Hey people lighten up! I'm just a DIYer. I just thought I wanted to push the limit from modding modules to making my own modules. I just wonder if at a global scale, would people get some knockoffs? Oh btw, my RM100 is made in China. I don't know how to reconcile "**** China, more people in...

How much do you think? Maybe that'd make me end up selling modules just as expensive as the real ones.

Ok. That just shut me up. :oops:
