Tom and Alan, thank you for your very helpful comments. I do have fans in my T4XC and also my TR7 and they work well. I mostly use the SP75 with the TR7 and it works fine. I really would love to buy a DX Engineering processor for the T4XC but they are very very rare-maybe one day I will be fortunate!My main concern,aside from protecting the tubes is to keep the good audio quality. It seems to me that lots of present day transceivers are badly adjusted by operators ,with excruciating results-I don't want to end up like that! John. GI3KDR

If you use it at settings which actually improve your audio, I don't think you'll have a problem. My experience with a Sherwood 7-SP MK III speech processor installed in my TR-7 is that about 6 db additional gain before clipping is as far as I want to push it. Good luck with it.
