Randall Tube Amplifiers / RT100 Pre Amp Valves
« Last post by scottravenhill on March 19, 2018, 06:59:54 AM »
Hi Guys,

This has probably been asked a million time so sorry for being such a noob!

I purchased my first all tube amplifier last year, the RT100H.

I've had a lot of fun with it so far and did the pre amp tube swap mentioned in other posts, (p2 & p5 including covered valve) or (p1 & p4 excluding covered valve)

Anyway, recently I'm getting a lot of loud microphonic noise in the clean channel, so I figure its time for a set of new valves rather than just one, as I bought the amp second hand and have no idea how old they all are. I am also not sure if I need to replace the input valve or just the 4 uncovered valves?

I'm really looking for reccomendations of that to replace them with. There are so many options available its all a little overhwleming to be honest! I have been looking on

Any help would be greatly appreciated!

Thanks in advance!

Randall Tube Amplifiers / RT50C with a load box
« Last post by wilkinsi on February 13, 2018, 09:12:39 AM »
A) If I want to use the RT50C with a load box:
1) Do I have to modify the amp, so that the built-in speaker is muted? Please describe procedure if this is the case. Can I still easily and safely revert to using the in-built speaker if needed?
2) Do both the 8ohm and 4ohm cab outputs have to be connected?

B) I want to switch amp channels using a Line 6 Helix, but the footswitch port is not directly compatible. Is there an adapter I can buy?

C) Assuming I need to get these modifications made by a specialist, is it cost effective, or am I better off buying a head and separate cab? The amp is sitting in a shop, but no-one is interested, so I'm thinking of taking it back and modifying it.

Thanks in advance.
Randall Solid State Amplifiers / Asking for help. Randall RRM 2-200
« Last post by VSAT88 on February 06, 2018, 08:03:43 PM »
Hi, new here so forgive me please if I break protocol. I have a Randall RRM 2-200 and I would kind of like to get it back up and running. It is trashed completely out but I like it anyway . I cannot find a schematic/drawing anywhere even on the pay sites. It is a very simple amplifier as far as I can see and I am making good progress but I really could use a schematic for things like the OPT. The outputs have been changed and I have no clue what the originals were and that makes it hard for me to match for new. Anyway, thanks in advance. Jim.

Does anyone have any information on this amp?  I recently bought it with a guitar.  I can't find much info on it and was wondering what it's worth.  I already have 4 amps in the house so a 5th just isn't going to cut it with the misses.   ;D

Randall Solid State Amplifiers / Old Randall RG-300 info for a beginner
« Last post by Meaningismuffins on January 29, 2018, 05:47:46 PM »
Hello, I'm looking into getting my first amp head and was wondering if the Randall RG 300 solid state amp head, (The old version with the orange stripe across the front) would be a good pick. I mainly play punk, sludge, grind core, or any rock and I found one for what seems to be a bargain. I've heard these things are pretty loud and sound great and was wondering what those with more experience think of them, or if it would even be useful for what im doing.
Also would I need pedals to be able to get something like overdrive or distortion on this. I only know guitar from playing my friends and I know enough now that I want to get my own.
Apologies if this is unclear to you all.

Im sure if I buy some 4 ohm cab this thing would work good, but how many watts would this be? [img],c_limit,e_unsharp_mask:80,f_auto,fl_progressive,g_south,h_620,q_90,w_620/v1511122484/kptmmfgifzktcgtrswn2.jpg

Hello everyone !

So here's my problem : I'm currently trying to sell my Randall bass amp, model RG-120-610 (200 WATTS), but unfortunately i can't find much info about the amp online !

So, i don't really know what would be a good selling price for it.. (Been used a lot but still in good condition !)

I've been trying some french forums since my native language is french, but most told me the best place to ask would be the official manufacturer forum, so i'm trying my luck here :P

Here's a picture of the amp in question, so you clearly see the model :)

Any replies will be greatly appreciated, thanks !

Randall Speaker and Isolation Cabinets / Randall RS-412 XJM Speaker Cabinet
« Last post by iamtetsuo on November 29, 2017, 01:09:48 PM »
A few months back, I got a good deal on a Randall RH300 G3 amp and matching RS-412 XJM 300W cab... I've got a killer tone from the amp and I'm just wondering what speakers the cab has. I've read different things, with some saying they have"Jaguar" speakers, others saying "Custom Eminence Jaguar" speakers and some even saying "Celestion Seventy 80" speakers. When I removed one of the speakers to see for myself, the back of the speaker simply said "Randall Loud Speaker". I haven't read anywhere that these cabs come with standard Randall speaker, so I'm left wondering what they actually are.

If anyone could shed some light on this, I would be most grateful.
