Tech-Master NIB TV Kit #5516

[Crist Rigott]

Here is something I ran across that I could use some comments on.

The schematic on V6 the 12BY7A tube, a wire shown connected to pin 9 and then a comma and then 3. I think this wire (B-) goes to both pins 9 and 3. At least according to the schematic.

On the instruction sheet 2 there is no mention to run the jumper from pin 9 to pin 3 nor does the pictorial on the same sheet shows it. I'm guessing that the instruction sheet missed that little jumper. Or did they? Is it needed?

I looked at an Emerson schematic which closely resembles this TV and sure enough, the wire goes to both pins 9 and 3.

Should I put in that jumper?

[Crist Rigott]

I just found out that pins 3 and 9 are jumpered in the tube. Nothing else goes to pin 9 so no jumper is needed to be added.

The instruction sheet and the schematic were both correct.

Yeah, I am.

Already I have a better understanding and appreciation for the factory worker who assembled TV's in the 50's!

They typically did the same 1, 2 or 3 functions - you're mimicking the whole dang factory!

Yeah, I think what it takes to get one of these into production. Every single step has to be built in, workers trained, QC, and testing, parts suppliers...Whew!

Though I do think I'm having more fun though!

His attention to detail still impresses me! I used to be almost that good.
I think, he's teaching some of us old dogs, new tricks.
RE: the speaker connector, many sets of the day, just used RCA phono jacks and plugs.

Thanks for the kind words.

Great idea on using a RCA phono jack and plug!

I'm working on setting up a file sharing system so you guys can down load the full set of documents including the 6 step-by-step instruction sheets, the step-by-step instruction sheet for the IF Strip, the Instruction Booklet, a large copy of the schematic, Supplementary sheet, and any other document that came with the kit. Eventually, I'd like to get the docs to the ETF.

[Crist Rigott]

OK. I uploaded all the docs that came with the kit. They are:

Instruction Sheets 1 thru 6. Full size 17x12
IF Strip Instruction Sheet. Full size 17x22
Schematic 11x17
Instruction Booklet
Parts List
Supplementary Sheet

You should be able to DL all the files I put there. CAUTION! Some of the files are about 7MB each. They are high def files.

Let me know how this is working for you.

https://www.dropbox.com/sh/v5ow2i7x8...rbUlywh3a?dl=0

Once at the file list, click on the file, then when it opens, click on "open" in the upper R/H corner of the screen. It should open as a pdf. Then click save as and save the file.
