BRAIN BELCH

waltcates All Messages By This Member #32145 开云体育 You know, sometimes a fellow needs?to follow his own advice.? I have been working on an SR-160. As of this morning I had put 12 hours into it. I was getting nowhere. I spent considerable time ensuring that all alignment was perfect. Every time I turned it on it acted differently. I don't know why, but?I started wiggling tubes. Almost every tube brought forth loud crashes from the speaker. I said to myself "Well dummy clean the tube sockets and pins".? Guess what, I now have the sweetest running SR-160. The receiver is running 22 to 26 db s+n:n. The transmitter runs 120 to 135 watts across all three bands. Well, that was my last rig on the shelf. So now I am looking for another project. I have not had a HT-40 on my bench for 15 or 20?years. So, I am looking for a complete unit. It doesn't need to function as long as it has not been butchered inside and has a readable front panel. So anyone with one that has been on the back shelf for years and is willing to part with it contact me off forum. ?73 Walt Cates, WD0GOF ? A majority of acceptance is not proof of correctness.

I know I don’t have to tell you that, DO I??? do you really count time. It would be depressing for me; so put the clock out the window. Oh I just wanted to say good going again. ? toggle quoted message Show quoted text From: [email protected] [mailto:[email protected]] On Behalf Of waltcates via groups.io Sent: Tuesday, April 15, 2025 4:07 PM To: HALLI IO GROUP Subject: [HallicraftersRadios] BRAIN BELCH ?

edward schumacher All Messages By This Member #32147 That's great, Walt. I have encountered a couple of? noisy sockets in this SR-150 but have yet to get such good results. Did the voltage checks around the Driver and Finals finding that with 120VAC from my line the supply voltages are all running higher than what's given in the chart. 270 instead of 250 for example. The HI B+ is 657 no load, 625 in MOX and 600 under key down. With 140 ma indicated that translates to around 84 watts. Still below spec I believe. Don't currently have a scope that I am used to working with right now. My old ones died and have not really learned the latest replacement yet to make the measurement you suggested. At least getting consistent responses now. 73 ...
