Title: Slow but steady... Post by: Ed/KB1HYS on October 04, 2009, 11:09:35 AM Update on the BU-250 Rig here (a 4-250 based AM rig). (BU stands for Butt-Ugly).
Finally got some more work done on the HB rig here. Got the meters into the plate circuit (plate volts and Current) and got the screen bias volts up. Found some transformers to get ~200volts for the grid bias. Now to work up the rest of that circuit, and wire in the meters for both. The Vp & Ip meters are mounted in the front panel of the power supply. The rest will be in a separate "meter" panel. Have to wire up the Soft-start circuit as well. Hope to have all the DC supplies & meters done today so I can start work on the RF deck next. Title: Re: Slow but steady...

Moving Trannies right now is no easy feat for me it's a bitch only weighing a 130 pounds.

I put the radio building off for a bit and enjoyed the day with my daughter (she's 11). The radio's will be there waiting, kids not so much.
