Hi Mike & Hal, You may find this post cogent: http://lists.contesting.com/_amps/2005-02/msg00325.html 73 & Good morning, Marv WC6W **************************** -- "m.ford" wrote: Gee, I didn't mean to start a fire but I guess if I am going to trash them I should at least back it up. The RS-50 is s/n 9402245. I bought it back in the mid 90's and when it self immolated I wrote to the company explaining how I felt about it. Someone called me up and spoke about it for a few minutes and I suggested not mounting the board on top of the cheap cap (s). The RS-70 is s/n 98080093. I bought it back in the late 90's and when it started to smell I took the cover off and saw the familiar pc board mounted on top of the familiar cheap cap. I saved the board and replaced the cap with two other ones. When I went to adjust the voltage I found no such adjustment, just a resistor to change. I guess the expensive potentiometer was more important to get rid of than fixing the potential fire hazard of putting a roof over the filter cap. I do have a lot of their other smaller stuff and I have no issue with those other than the stiff power cords. But the big stuff ain't up to my expectations when dealing with large amounts of DC current.
