Adee Posted July 14, 2022 Share Posted July 14, 2022 (edited) Anyone else have / had an issue with the knobs breaking on their RH450 / 750 Amp? The plastic used in manufacture at the time, maybe still? becomes brittle and easily breaks after some time. TC used to replace the knobs and buttons but now they seem to have shirked that responsibility, so you are left with trying to source them yourself or replace them with another type. I remember Hercules had an issue with their plastic becoming sticky on their stands and even now they will still (with a bit of pushing) replace the part for free. Shame on you TC very poor of them !! BTW If anyone has 2 or three spare knob drop me a message please Edited July 14, 2022 by Adee Quote Link to comment Share on other sites More sharing options...
Muppet Posted July 15, 2022 Share Posted July 15, 2022 Common problem. I think TC slowed up replacing them when they sold out to Music Tribe. I do have these knocking around if you're close to MK. I'm in the middle of a house move so can't be bothered to head to a post office at the moment! 1 Quote Link to comment Share on other sites More sharing options...
Woodinblack Posted July 15, 2022 Share Posted July 15, 2022 Yep, one of mine broke / fell off, I just ordered a load more as they were pretty cheap, before I found out they would send the replacements free! Unfortunately they were in a box of things that my pigeons knocked over the other day while fighting and I haven't had a chance to dig them out yet. I know, first world problems!!

Woodinblack Posted July 18, 2022 Share Posted July 18, 2022 Note there are two types of knobs, the volume knob and all the others. They have a different mounting 1 Quote Link to comment Share on other sites More sharing options...

Adee Posted April 15, 2023 Author Share Posted April 15, 2023 Music tribe are a waste of space, I even had contact with a guy at TC who was helpful, sympathetic but still couldn’t help !! Quote Link to comment Share on other sites More sharing options...
Captain Bassman Posted April 18, 2023 Share Posted April 18, 2023 Same problem here. I need a full set of replacement knobs and a couple of encoders (broken shafts following a rather short fall..). Music Tribe are completely useless. After a long wait they eventually sent me the names of 2 ‘authorised’ repairers who can source the parts. One said they didn’t work with MT so couldn’t help and the other (Ampman Audio) has been very helpful but the process is so slow. Not their fault as they have to get the spare parts from MT… Why on earth MT can’t just send the parts directly to me I don’t understand. So far it’s taken me 6 months. I paid the invoice for the spares on 28th February and am still waiting for Ampman to get the parts in. Totally ridiculous scenario for such a simple fix.

Exactly the same scenario for me, contacted Ampman and was given a quote for about £60 to get the knobs, sooooooo I politely declined their kind offer The very helpful fella from TC and his colleagues in Denmark even drew a blank which was amazing Quote Link to comment Share on other sites More sharing options...
Killerfridge Posted April 18, 2023 Share Posted April 18, 2023 TC told me that I needed to send them the amp for a full "service" in order to replace the knobs. I've instead started replacing them with completely different ones that fit the same stem for pennies! I just need to replace the snapped stems now...

Its a pain, they used to be really easy to replace just contacting TC. For the shaft you can either replace the pot, which I would imagine isn't an unusual one, or just get some plastic shaft material, try and match the end and glue a new one on. Or like some I have seen, put a screw through it! 1 Quote Link to comment Share on other sites More sharing options...

I actually really like the "new" look from the white faced replacement knobs, and they feel a lot sturdier too! Quote Link to comment Share on other sites More sharing options...

BassmanPaul Posted April 27, 2023 Share Posted April 27, 2023 I feel that the knob issue is a stunning failure of design elements by TCE. An owner should NOT have to go through these trials with what amounts to a new amplifier. 1 Quote Link to comment Share on other sites More sharing options...

The amp is such a great bit of kit, it's such a shame they cheaped out on such a fundamental part of it 1 Quote Link to comment Share on other sites More sharing options...
