August 1968 Sears Silvertone Silver Sentry color stereo combo

[pac.attack76]

Just got this the other day and spent the last couple days cleaning everything. Haven't been able to test as there are about 3 tubes missing and one broken. I have several replacements but the diagram is missing so I have no idea what tubes I need. I've been wanting an older color set with radio and turntable. Found this in an abandoned 1972 mobile home that's been sitting for decades. Among this was 70s GE console TV, a table top Emerson 19", another"19" JC Penney set, an old Juliette clock radio, A brown GE refrigerator, a brown Montgomery Ward 850 clothes washer. A 1972 coffee table and matching end table with gold velvet inserts in the doors, an orange foot stool. Even an old Montgomery Ward window ac. Plus a lot more. Even the bathroom was all yellow fixtures. Never remodeled. A real time capsule. How do I find out what tubes I need? I think model is 7194.

That chassis is an RCA clone (probably CTC-17).The high voltage rectifier is a 3A3, the broken shunt regulator is a 6BK4, the missing novar chassis mounted horizontal output is a 6JE6, and the nine pin circuit board mounted tube is a 6KA8.

Ty friend. I'm pretty sure I have some of those. I'll check tomorrow and update.

Wow very nice Silvertone set.

The 4 digit model ## is useless. Look for the long number on
a plate, format is ###.###### its the source code.
First 3 digits are the MFG ( Warwick in this case) then look up in Sams.
The Horz out is expensive so check the CRT first.
Also cant be sure but the HV cup looks chewed up & the shielding
is missing......

I had a feeling that 4 digit number wasn't gonna be right. Only thing I could find. I don't see anything on rear cover and not sure if it has anything inside. Could it be on chassis anywhere? I did notice that cup had saw tooth marks. Done at factory? Is shield mandatory?

I have the 6KA8 as shown installed in the pic. I have a 6BK4B but I don't think it's supposed to black? Only others I have are 6BQ6GA/6CU6, 6MJ6, another one similar to the 6MJ6 but slightly taller and the numbers are missing but a 6, 31JS6C, 6DW4B, 6MD8, another one similar to the 6MD8 but no id, HJ359? Hard to read, 12AX7A, 6AU6A, 6AQ5A, 6GHBA, 6DT6, 6FQ7/6CG7, 6LM8A, another one similar to 6LM8A but no id, 10GK6, 10GV8/LCL85, 5**7 can't read, 6*Y6, IV25?, 6GM6, 6EJ7, 6GM6, 6GY6, 6GH8A, 6MQ8, 6G*8A, 12GN7A, 3GK5 and a 20AQ3 with a white top- probably blown.

The tag will be on the chassis. The HV cup was probably arcing &
to save time, money & ordering one was chopped away. ( moused). Best to find a Sams before spending any $$ on it.

The only time the 4 digit model is useful on a Sears is when you have a nearly complete Sam's library and you strike out on the longer number.... Having a complete Sam's library is necessary because Sears reused those 3 digit model numbers so you'll get multiple hits under Sears silvertone and have to pull several folders in the neighborhood till you find the one....Had to do that on a Japanese made Sears tube color that the long number didn't seem to be indexed for and it was a pain (successful but a pain).

The black 6BK4 may be okay. The 6MJ6 is a sub for the 6JE6, we stopped buying 6JE6s when the 6MJ6 became available, at the time they cost about the same and the plate caps didn't come off!

[pac.attack76]

I'll put the other 2 tubes I have in. Looks like I'll be missing one. I was able to find a Sam's sheet online for $10 plus shipping but I can't afford it right now. I think it's the right on. I might be wrong though. I included a pic of it.

That Sams you posted is not the right one for your set. Set number 977, folder number one is a series string set, no power transformer. Set number 961, folder number 1, and set number 965, folder number 2 are closer to what you have.

Ah ok. I couldn't find anything else.

My Sams paper index from 1971 lists Sears model 7194 as being in set number 943, folder number 2. The cover picture is a combo.
