Yesterday I was playing through my RT2/50 and at some point the volume dropped out. I was playing wireless and thought maybe a battery had died. As I went to check my wireless transmitter, the volume faded back in slowly....I'd say it took maybe 5 to 10 seconds. Then all was fine for the rest...

XTC module. Silverface black stripe. Clean condition except two of the blue caps appear to have soldering iron burns. The module functions fine. As a matter of fact, I just played through it and it sounds great! I bought this from another forum member a few years back and I think they said...

Anybody with an R212 cabinet got a picture of the cabinet from the backside with the 1/3 removable upper panel taken out? Thanks!

I just got a Top Boost module and am considering having some mods done to it. I'm really surprised how much gain this module has and I'd like to be able to also get less gainy sounds, so I like the idea of the AC30 switch. I'm less sure about the bass switch mod and the cap upgrade for this...

Don't know if these have been posted yet, but I hadn't heard them until now: http://fr.audiofanzine.com/produits/tests/index,idproduit,72459,page,3.html That review is linked from the Randall website. It is in a foreign language (French?), but the module names are clearly listed. BTW, if...

Has anybody out there directly compared a Mr. Scary module to an SL+ with the tone stack and .001u cap mods? Also, does anybody have a top side picture of a Mr. Scary with the tube shield removed? I have a hunch the circuits are very similar.

Well, I finally did the JCM800 tone stack mod to my silverface SL+ module. I changed R31 to this: http://www.mojomusicalsupply.com/item.asp?pid=85926&pg=45001&id=7294333 C14 to this: http://www.mojomusicalsupply.com/item.asp?pid=96053&pg=44974&id=5168225 While I was at it, I also did the cap...

I now have both and after comparing them, I have to say that I like the Plexi module better. By reading the Randall descriptions, I thought the SL+ would be the perfect fit, but not the case. In comparison the SL+ sounds too sloshy/loose. The Plexi is much tighter sounding and versatile...

I was just looking at them in the "Randall MTS Module Modifications" section of the Grailtone site a couple nights ago. Then last night I looked and they were gone. Am I overlooking them?

I just bought my first blackface Randall module (an XTC)....my other 3 modules have the silverface. Anyway, check out this pic: Is it normal for the capacitors to get burnt like that in manufacturing? My silverfaces don't have that. Anything to worry about? A couple other miscellaneous...

I own an RM50B combo and still have the factory 6L6 tubes installed. I just got an SL+ module and want to try some Marshall-y tubes. I also run a Blackface module. What EL34s would you recommend for that combination? I want a decent clean sound to work with the Blackface. Also, the tubes...

I was just reading about the SL+ JCM800 tone stack mod on Grailtone, then took a look at the PCB layout PDF file for the SL+. That layout already shows R31 as having a 33K resistor....and C14 having a 470pf cap. Does that mean Randall has started shipping the SL+ modules with the...

The Randall website says that all MTS cabinets have a jack plate with the Mic Eliminator and outputs that allow for 4 ohm mono, 16ohm mono, or 8 ohm stereo. I just saw a pic of an R212CB and it has 8 ohm mono and 16 ohm stereo as the only options. This one has silver cloth so it's one of the...

See here: http://randallamplifiers.com/accessories/accessoryparts.asp I'm wondering how good the quality is. $34.95 seems like a good price for a cover for my RM50B.

The footswitch that came with my RM50B works fine, however, it doesn't have any sort of light indicator to help with knowing what channel you are on. That doesn't matter when playing at home and may not matter for some live music, but in more subdued environments (church, etc.) it is nice to...

I bought my Blackface module (silverface front panel) pre-modded and was looking it over last night. I found that there were TWO resistors in position R1. I searched the web trying to decode the different color bands to find what value the resistors are. Here is a decent resource for that...

Let me know if your SL+: -is silverface or blackstripe. -has been modded or not -has the original box/packaging -price Thanks! Chad

Just wondering if any of you have tried different speakers in your MTS combos? It seems interesting that the regular MTS cabinets come with Vintage 30s, yet the combo amps come with G12T-75 speakers. Also, the Randall website says that the RM50B comes with an 8 ohm speaker....mine actually...

On my RM50B combo the tolex is fine in most areas except the back panels. Randall should have wrapped a little tolex around to the back of the panels, but instead they stopped right at the edge and, not surprisingly, the tolex is lifting pretty badly. I'm gonna experiment with spray adhesive...

I'm trying to understand how the series and parallel loops interact within my RM50B (I think it's probably the same for all of the MTS amps, though). Okay, a person is using both of the loops.... Signal leaves the preamp, then how are the series and parallel loops arranged? The manual makes...
