thermocouple for Thatcher furnace

Have an old Thatcher furnace, cica 1950's. Does anyone have a clue where a thermocouple for this dinosaur can be bought. Is there anything on the market today that can be "jerryrigged" if an OEM equivalent is not available.

Hate to get rid of it. Going by heating bills, it's as efficient as all these new things. The way its built, it looks like it'll make it for 50 more years. Intake BTU's are 180,000 and going out 140,000. Told nothing on the market today is that large and that I'd probably need to put in two furnaces to replace it for the house.

Any help really appreciated.

Thanx

At one time, you couldn't buy them in my area unless you were a contractor. But now they have them right on the shelf.

Usually around $8 or $10 depending on the store and the time of year.

Thank you for the reply. Unfortunately, what's on the market today is not a "drop-in" fot the Thatcher. The thermoucoule head which sits in the pilot-light of the Thatcher is much much thinner than the heads of the thermoucouples that can be purchased today.
Guess I'll have to figure out a way to retofit a new thermocouple to the Thatcher but concerned about safety.

Thanks again

Are you able to post a picture of the pilot and thermocouple?

What I'd suggest is having a pilotless ignition kit installed on the furnace that lights the pilot each time the furnace calls for heat.

Eliminating the standing pilot probably saves $8-10 in gas per month. Honeywell makes this kit that can be retrofitted on most old pilot burners.

Alternatively, I'd replace the obsolete pilot burner with a new pilot burner and thermocouple.

Thanks

All

Wow, great ideas. That is a lot of money to save. Can't quite figure out hot to get a decent picture but I'll try.

Thanks again

I think your furnace probably used a" Penn-Baso Husky" thermocouple as original. Most any thermocouple can be used as long as it has a male end and not a "split nut" style connection. All t'couples come with adapters to install in various pilot burners.
