I know I am new to this forum but have you checked with Digikey or Grainger yet?

I am an electronic engineer hobbiest and I get almost all of my stuff from Digikey, Grainger or Mouser.

Yes, I’ve been through Vimex’s Distrbutors, digikey, mouser, jameco, 1sourcecomponents. 3 Chinese companies. Most can get the ones i want but my minimum purchase is 3k of them @ $5500. My last effort is the mouser quote. I’ve delt with mouser since late 90’s so im hoping they can aquire them and keep them in stock. Then alot of people have access to the good parts without getting it inserted and broken off.

Well Mouser was a bust. they cannot source them Under 3000 pieces minimum. Im calling it. I have been beaten. not that i couldn't find them but i can't afford them. i can get the blue ones fairly cheap. if the originals lasted 10 yrs how many times would they really need to be changed?

So where can you source the blue ones at? A pot you replace every couple of years is better than no pot at all.

Bob when you get a chance, take a look at the Drawings section, particularly VD7,5 and VD11 and verify the measurements so i can make sure i get the right model. and they are Linear taper. Im going to order the normal cermet just not the long life.

They are vd11.The numbers posted in your quotes look right to me.I see the standard cermet has same life cycles as the blue carbon,but,looks like they are readily available.I will buy 1/3 from you,if you like,for people at this end of the country.

I'll definitely purchase a handful from you against future stove repairs. Let us know the details for payment, etc., when you have them.

Order was submitted today. They should get it tomorrow morning. They are the mid grade cermet pots not the long life. But they will be available soon
So did the pots arrive?

I have to email the site owner and see where i stand on being able to sell them here or if i have to become a site sponsor. 7.50 and it is 8.00 for priority mail[/QUOTEAs you are not a business,and not making a profit,i should think they will not mind,but always best to check.

Once you get things figured out I'd like to get three..
Not sure what works for you back when I was selling cables etc for the Bixby Stove I gave the customer my address and they sent me a check. Then I sent what they bought., My e-mail is rahfanderson@outlook.com .

I’m curious how many Harman boards you fellows have come across with bad pots. I’ve only ever come across a couple of them, and I’ve got around a thousand Harmans in my service area.

There are a few. but i tracked down the elusive pots for forum members and friend to save them the $$$ the Ebay sharks are charging. Making a profit is one thing but when they charge as much for 3 as it costs for 60, Thats just taking advatage of folks.

I have a P43 purchased new in 2008 and it took the pots 12 years to start acting up. Last winter was a real PITA running the stove as the pots were acting up so bad there were times when I could barely get any heat out of the stove. The feed auger would run about 10 seconds and that was it regardless of the settings. Trust me the issue is real for some folks. Could be a bad batch, who knows but after replacing them I tested the stove and the test indicated I will have my heat back this winter.

I am one of the fools that paid the long price for the pots but I needed to just get it done as my son, who is an electronics technician, was visiting over the Fourth and I took advantage of his soldering skills and sharper eyes.
