Hi, I've had a similar problem in the past. Mine turned out to be the big plastic Randall badge on the front. I unscrewed it, put Prestik (SA equivalent to Blu Tac) over the back of it, then screwed it back on. No rattles since then. Since taking the grille off didn't help, you have a different...

I know this is an old thread, but has anyone got a few sound clips of the XTC modded this way?

****. Awesome sound though. Very similar to what I'm looking for for my rhythm, and I'm keen on modding my Plexi.

Oh cool. I'll definitely give it a try then. Most of the time, I'm playing at night when the family's asleep, so I usually don't get to crank the volume too often.

Really? It seems a little quieter, but maybe that's got to do with the impedance. I didn't hear anything out of place when I was playing, but I'll give it a play with the switch on 4 ohms a bit later. The reason for running 50W was that one of my tubes was broken when I took the cover off the...

Oh ****. Of course. Can running it like that have damaged anything? I didn't put it too loud because I was playing at night, and I didn't play for too long either...

Nice! Is the R25 the only component you've changed, or has it been previously modded? Also, is it an old (Silver face) module or the newer one?

Yes, it gets halved. I kept the cable in the 8 ohm sockets and flicked the switch over to 16 ohms. Glad I found out about that - it's not mentioned anywhere in the manual.

Hi all. I've decided to give modding a try. I'm just a bit stuck at the moment. I've got the Blackface, Plexi, and XTC modules, which came standard with my amp. I like the Blackface as is, but I may consider the "Clean" mod for it after I try it with high output pickups. My real decision is...

OK, so I fired it up for the first time in ages this weekend, and everything was fine. I checked the bias, which I actually had set to 33.4mA, not 38. I re biased down to 31mA to be safe, as we've had all kinds of wild power fluctuations recently. The fuses seem to have been the issue. Either...

It's meant to be a 2.5A fast blow according to the manual, but I only had the option of 2A or 3A, so naturally, I went lower to be safe. I've just got a bunch of the correct fuses and it started up fine. I had one tube go (I think the cat must have bumped it or something because it's cracked in...

Thanks man. I'll re-check the bias when I have more fuses. I must have made a mistake above - I made sure the bias was within the range listed for 6L6 in the manual. Our power is always up and down because of illegal connections on the power grid, poorly maintained / completely neglected power...

I forgot to mention - here we run on 220V @ 50Hz in theory, but a check with a multimeter over a few hours usually reveals a true output of anything from 215V to 239V, so I set the amp to 240V to be safe. I'm planning on running my amps off a pure sine wave inverter in the future though. Yeah...

Greetings, all, from Durban, South Africa. I've had my RM100 since Dec. 2009, and it's been blowing power fuses under certain conditions for ages. When it's been standing for a day or two, it starts up without fault. If it's turned off and on again within what seems to be 8 - 12 hours, the...
