jay42 Posted September 26, 2021 Share Posted September 26, 2021 Hi folks Last night at my gig, I unpacked my trusty RH750 head and discovered that the bass eq control knob had split in two and fallen off, does anyone here know where I can get replacements? I've had a look on everyone's favourite auction site but to no avail...any help would be much appreciated! Quote Link to comment Share on other sites More sharing options...

warwickhunt Posted September 26, 2021 Share Posted September 26, 2021 They are notorious for splitting and dropping off... slightly worse than Warwick's chocolate jack sockets! Quote Link to comment Share on other sites More sharing options...
M@23 Posted September 26, 2021 Share Posted September 26, 2021 Yeah this was a thing a few years back, I’d message TC first off. Quote Link to comment Share on other sites More sharing options...

Bass Wielder Posted October 21, 2021 Share Posted October 21, 2021 Heyyyy. I would be interested to see how this goes… I had a similar issue with my RH750 in 2016 (still have that amp and love it!)and they did send me some knobs. However those broke as well so I got some aftermarket ones and they are still going strong. Now new issue, the surrounds on the push switches are all split/cracked (with just time not impact), so I want to replace those. Hopefully that can help….

Would you mind linking to the seller so other of us RH750 owners can join in? Love your colour palette too! Quote Link to comment Share on other sites More sharing options...

Love your colour palette too! Thanks! Where I got those…..not sure. A friend sourced them from an electronic shops he buys from (like RS elec., etc…). I suspect sturdier knobs like from a mixer would be good (as long as the shaft diameter is similar). I believe my knobs are screw fixed into the shaft (as opposed to push fit). I’ll double check… Quote Link to comment Share on other sites More sharing options...
bagsieblue Posted October 27, 2021 Share Posted October 27, 2021 I replaced the knobs and buttons on one many years ago, following this ( though not seems the photos have been lost): Quote Link to comment Share on other sites More sharing options...

BassmanPaul Posted November 6, 2021 Share Posted November 6, 2021 You really shouldn't have to go through this crap with what is supposed to be a good quality amplifier! 3 Quote Link to comment Share on other sites More sharing options...

Agreed!!! This is the longest I have kept an amp head because I really do like it (tones and functionality). But shockingly shite knobs!!!😡 They literally break like biscuits!! Hence my posts to help others with this crap…. 3 Quote Link to comment Share on other sites More sharing options...
BassmanPaul Posted August 11, 2023 Share Posted August 11, 2023 (edited) It doesn't matter how good an amplifier is if the 'packaging' fails in normal use. The knob problem should have been discovered and rectified during initial testing of the prototypes.

Stokey Posted August 22, 2023 Share Posted August 22, 2023 I know this is an old thread, but I’ve experienced the same problem with trying to source replacement controls. TC recently referred me to a Uk supplier who emailed me as follows: “We no longer have stock of this item and Music Tribe (TCElectronic's parent company) have the product and parts for it listed under the 'Legacy' catergory. They are all marked out of stock so unfortunately we can not order these for you.” Useless! Quote Link to comment Share on other sites More sharing options...

MT referred me to a UK ‘repairer’ who I contacted last October. As of 2 weeks ago they were still trying to source these replacements but were getting nowhere. So… I dropped MT’s CEO (a certain Uli Behringer) a stern private message via his LinkedIn profile thinking it was a long shot. He replied within 20 minutes and from then on put me in email contact with a couple of people in the Customer Service Centre in the Philippines. Basically the 750 and 450 were discontinued in 2019 and ‘due to COVID’ spares and their shipment became depleted. Long story short, within 1 week I had received 20 new knobs (10 of each type), 10 new encoders with shafts and a fully loaded new circuit board ready to drop into my broken amp. All gratis. It took 10 months and I wish I’d done this earlier. I was on the verge of ditching both my 750’s and looking elsewhere. Apparently they are ‘now ramping up’ the supply of spare parts for these heads. Give Uli a shout. You never know… 1 Quote Link to comment Share on other sites More sharing options...
