1. [TenTec] Model 260 PSU problem (score: 1): Author: "Steve Hunt" <steve@karinya.net>; Date: Fri, 1 Dec 2006 19:23:22 -0000; Folks, It's turning into "one of those weeks"! I couldn't understand why my new Omni VI was "unhappy" at full power when fed from my Model 260 PSU, but was fine on the Hercules II supply.

I have catalogues for all the main UK component distributors, but none stock a diode bridge in the same package as the one in the Model 260. It's a package I've never s; /archives//html/TenTec/2006-12/msg00004.html (9,564 bytes)

Never in the solid though. Likely the flange matches a TO-3 case. So I guess you need a new hole in the heat sink right in the middle. -- 73, Jerry, K0CQ, All cont; /archives//html/TenTec/2006-12/msg00005.html (8,181 bytes)

I'll keep an eye on the Diode Bridge case temperature for a few days to check the heat-sinking is OK. Yes, I drilled a new hole mi; /archives//html/TenTec/2006-12/msg00009.html (9,457 bytes)

The half wave rectifier puts unbalanced DC in the transformer and that biases the core so it's certainly running much further into saturation that it was designed for.
