[Amps] SB 200 blown diodes in power supply

[Kathy Bookmiller]

I know many of you probably consider a SB200 as a driver for your real amps, but for us QRPers, it is as good as it gets:)
I just blew a diode in HV chain. Now one friend I respect says I should put in the Harbough board, soft start, etc. Trouble is, that's money I don't wish to spend if I don't have to. Put in new board is easy to say when you have money, but us poor underpaid nurses....
Taking a look at mine, I noticed there are 3 diodes already replaced in the two strings by placing them under neath or on the bottom of the board. When I first looked at it, I thought they had been vaporized:), so this isn't a new problem.
I'm hoping to find something at Radio Shack I could use and just change out the newly blown diode, maybe even using the trick the previous owner employed of just putting in the new one underneath to save taking it apart to get at the top of the board.
So was wondering what you guys think or your experiences with the SB200. I just acquired it last summer and otherwise has worked really well when I've needed it.
