Hi guys, I just checked this thread for the first time to see if there was any info on biasing an RG50T (I'm mainly an MTS fan) and I found your discussion interesting and useful. So, the reason I was looking is because I wanted to try a set of 6L6's to see if it improved the clean tone. I...

I got a Tuki padded cover made for my RM50 combo and it fits great. Just fill out the form they have with the dimensions of your head and they'll make one to fit. I think I paid around $70 for mine and it was well worth the price.

So, to expand on this, does anyone know if the extension output on the Randall head is wired in series or parallel with the main output? I have an RM50 and I presume it is the same as the RM100... I think most amps have them in parallel, but I also have a MusicMan amp that has the outputs in...

Guys, I built a pedal similar to the schematic posted and it works great. The only thing I did differently was to use an audio taper 250K pot. I found that I could have better control over the level of boost. With the linear taper it gets loud quickly. The other thing I did was to...

That's great! Thanks a bunch. Dave

Bruce, no I haven't seen your answer. I'm still interested though. I have a rectifier/filter built, but I haven't tested it under load (on the amp) because I don't know what the limitations/issues are for the 9 VAC supply. Thanks, Dave

Bummer. That would have been very convenient. I forgot to mention that I wanted to do this INSTEAD of powering the reverb circuit. Does that change the answer, or is this just a bad idea for the amp itself? Dave

RD guys, I know Randall doesn't release schematics for their amps, but can you provide specifications? Specifically, I'm interested in the power rating of the 9V AC output that is used to power the reverb tank. For fun I rectified that output to produce 9V DC to power some effects units I keep...

Here's something to consider - I had Pete (okstrat) do a mod on my Blackface to give me a "deluxe" setting. I wanted something with more gain than I could get with the Blackface without having to give up the Blackface. Pete's mod was just the ticket for me. I can now switch between a twin and...

Sure, I'd be happy to provide more information about the "footswitch boost" modification. I'm happy to send pictures, schematic, etc. Please PM me with your email and I'll send stuff along. --Dave

Actually, what I meant in my last post was to say a 250K pot not 250M! Sorry for the glitch. Anyway, I'll take this opportunity to also mention that when connecting to the volume boost 0 ohms gives no boost and 250K gives maximum boost, so if using a footswitch like I mentioned above, the pot...

I have a Randall Tweed module that is hardly used. Anybody interested in a trade for any Marshall-type module - Plexi, SL, JCM... Dave

Hi Guys, I have an RM50 and I find the boost function great for adding just enough boost to bring leads out front. Instead of using a volume pedal, though, I just added a 250 Meg ohm audio taper pot (pretty much all volme pedal are anyway) to a footswitch so that I can dial in the amount of...
