Does anyone know if the TR5 switch is common to the TR7 or other models? Mine has been bad for a long time and I have just jumpered it to get by.

I would not recommend a lubricant since it is switching power. Drake stocked the on/off switch cap part of the gain control and also the on/off switch cap for the R-4B. We replaced several of these in the service department. John Kriner has the R-4B switch caps in his store on ebay, he thinks the switches are the same. But, I'm not so sure, I know they had different part numbers, but I never tried using one for the other, as we always had both parts. If interested in getting a "spare" switch cap, contact John Kriner, The Man Electronics. 73, Bill wd8dfp _____
