I wasn't able to UL the Magazine but did see a copy of service manual and operator's manual for the SR-75 in the files section. Jeff K7AIL

Thanks John, I will hang on to this for awhile and make some contacts, maybe we will work. 73, Roger, NJ2R Sent: Friday, October 21, 2022 9:22 PM To: [email protected] Subject: Re:

Just a thought but if it is indeed choke input, you might consider putting the choke on the negative side if a bridge, or the center tap if otherwise. That way, way less voltage across the choke. Jeep

That's where my file came from. ?I tried to upload it a couple of times but was unsuccessful. ?It's about 18MB in size. ?Is the size fine?

I have not looked? but suspect it's on worldradiohistory.org? perfectly enormous amount of stuff there?Sent from my Galaxy

Looking around, I found a contemporaneous review of the SR-75 from "Radio and Television News" of April 1951. ?The whole magazine isn't too big so I'm going to UL the whole the . ?The review is in

Ok, I am going to probably show my ignorance of choke input power supplies but here goes!! I am rebuilding my HT45 power supply.? My HT45 is Hallicrafters branded but probably like many, has the

YES, it was an exciting time to be a new ham. The war was over, television was just getting a good start, telephone service to a home was sparse as it was usually a party line, private phone service

C. 1951 the S 38B was about $40 and the SR 75 about $80.? I don't know what that included in the way of accessories, extra coils, etc.? I got a brand new S 38b when I was a kid,? I don't remember

That's kinda cool! ?Those days were kinda different for starting hams. Does anyone know the difference in price between a S-38 and this radio? Depending on price, it may have been cheaper to use and

Hi Roger That is a great story and I've never seen one of those in person either. It certainly does sound like it was "meant to be" with your ownership. 7050 is a good spot for such a radio and I have

I'd known of the SR-75 for a long time as is it shown in the Chuck Dachis book but I'd never seen one though possibly passed them at swaps and thought, "just another S-38B". So, at the Chelsea,

An update on this. I removed the stripping and as far as I'm concerned the lighting looks just fine now. Will button up the front panel and call it good. That was really quite bizarre -- I was being

No. The strip is mounted below the glass. 73 – Steve, KW4H From: <[email protected]> on behalf of wb6ogd <garywinblad@...> Reply-To: <[email protected]> Date: Sunday,

Gary, Very good points, thanks! I took another close look at the dial, the markings, and how it’s mounted. It seems to be original. I can’t find any evidence that the bandspread window has been

Could the bulbs push further in?? To maybe get beyond the edge of the glass... 73, Gary WB6OGD

Its been a long time but I remember my SX-110 was lit and Bill's looks really correct to me. I know these dials have fragile white markings after all these years and I am pretty sure I have seen

Attached are pictures of my SX110.? The radio is on in both.? The foam is there I believe to force the light to go through the edge of the dial by design.? The cheap digital camera didn't like

I used a SX-110 for my Novice station receiver back in ‘67, and it was in mint condition, only a few years old at the time.,As I recall the slide rule dial is illuminated from the lower aspect of

Well, the plot thickens. I pulled the front panel and the spacer is almost certainly factory -- it's quite brittle and was attached to the front panel using very old glue (it started falling apart
