There's going to be a lot of weight when things are done - that's for sure. I'm using an L-channel under the chassis. This will be placed in under the front mounting holes of botn Tx's and the choke, thus fewer scwers poking through the top (thanks GarMan). Have you started to lay out the CCS? I ran into a concern last night the way I have things on the PC board. The output to the coupling cap and the power (B+ from MOSFETs) are pretty close together, about 1/2". I'm hopeing I'm not going to run into any problems with noise. I think this is where the shielded cable is really going to come in handy......Colin
