7 Transistor AM Radio Kit

I really don't remember a brand, the case was a brown plastic.

The Kelvin kit I have didn't have the transistors included. I looked at the bill of material and it didn't show the transistors. Seemed strange! The schematic shows all germanium types and it has a revision date of 1997.
I personally don't get it! The instructions stated to check to see that all the parts were present, but didn't show the transistor types.

I have pieces of the Radio Shack 8 transistor radio 28-222 that I got as a gift back around 1977 with the white or tan/brown case.As I found it a couple years ago with the PC board broken and parts missing .What a shame.For some reason I never completed the kit when I got it.

For some reason these current kits look cheesy to me as I compare them to the old Radio Shack 28-222 kit.

As years went by around 1983 I picked up the cheaper Radio Shack 28-4029 radio kit model in the black case with 2 transistors and a LM386 for the audio amp .It sucks compared to the original kit.

As I was doing alittle homework on these kits the other day .I found a couple posts on ARF about the Graymark version of the old Radio Shack kit .The model number is or was Graymark AM radio model 536.

I would love to get my hands on one of these Graymarks.

The 1970's RS radio kit had these plastic style transistors like in the photo in the attachment and not the old metal germ 2sb54-2sb56 style transistors.

I'd love to have back my RS Archerkit AM radio I assembled in '74.. It got traded off that Summer. I was just an 11 year old kid and more interested in tube radios then.

That Graymark one might be tempting though..!

Yea .I'm close to your age Capt .I like to check out the Graymark kit out since its a clone of the 1970's RS radio.They must of bought the rights from the Shack to continue with it.

Maybe somebody can chime in with any more info on the Graymark kit and obtaining one.

In high school, 1983 I built the Graymark AM radio kit. In class we built it on the included breadboard and after I took it home, I built it on the pic board and installed it in the cabinet, all included. It was a well built radio and a good performer. The kit is still available today just as it was and I have thought of building one for nostalgia purposes.
