I added a second BC212.

How do you like those BC cabs? Im seriously considering those exact cabs.
 
The more I play other peoples rigs, the more I like TCE rig! I still have not heard back from them about new knobs. Does anyone have a shortcut to getting some new ones?

Sorry, can't help you on the knobs...never had a problem with my 450 or 750 knobs, but I'm with you on digging it. I'm still wanting to try everything I can, but nothing has made me want to let go of the RH yet (2 Ampegs, GK, Genz Benz, Overton...no keepers yet).

My latest is a Carvin BX500. Really nice amp, but I spent some time A/Bing today and in relative terms, the "warmth" of the RH is simply sweet.

Eden and Markbass are on the short list.
 
Hi friends,
This week I have had repaired my RH450 by the official TCE service partner in my country. It has costed me 70 €.

They have changed a chip that has access to the main memory of the amp. Because of that chip the amp seemed to be burned out.

So luckily my RH is saved and ready to get gigged tomorrow.

Good to hear. Hopefully it was quick, successful and the cost was acceptable to you.

I haven't had any problems with the knobs or anything else in the 4 year my rh450 has been gigging around.
But I'm another one digging it. I've given up on gas as nothing speaks to me like the rh. P bass, flats and the rh450= warm rich mid goodness

There's a pretty nice set up Eden rig at one of the churches I play at and to be honest, I hate the thing. It's a 210 combo with a gazillion knobs and that sit on a 212 cab. I just can't get a tone out of it I really can say I like. It's 4 band with compressor and all that stuff. I just don't like it.

That is good to hear. Kind of problem you would not have been able to track down by yourself. That's nice they gave details about the problem. The amp really is awfully complex to work on. I did try to open it to try and understand how those class D amps work, but didn't went far, there is a two-boxes design, the inside one being partly structural for the amp and cards. Nothing simple like your hifi audio amp or an old point to point valve. Here the inner box is also a kind of emf faraday shield. The inside is divided in two sections, left when seen from the front, handle side is AD section, memory and logic I would say. This is separated by a wall through which the fan is sucking air. Right section is power parts, from mains to pwm switch amplification, to output, with big heatsink bolted on the heavy right external cover. So layout of front and back are totally unrelated to internal signal path. That's high level design this RH450.

Good to hear yours is fixed :)
