Most people 'harvest' them from old cameras; I hate to see working cameras turned into organ-donors - but I have to admit having no personal interest in a camera that old.

An eBay seller did take apart old cameras has two left at $45
Pentax K-30 K-50 K-S1/S2 K-500 Genuine White Aperture Solenoid Part - Japan - | eBay
When Sun Camera repaired my K-70 replacing the entire Diaphragm Control Block the part cost on the invoice showed $28.00 Canadian.

This is an image of my old part returned to me.
Cheers!

Well, yes, at us.ameras.com the entire block costs a little bit more, they made you a good price.
How much was the total? Replacing the entire block is lots of work. Replacing the solenoid is peanuts compared to it.

Nevertheless, the green solenoid is available, the diaphragm control block as well, but the Japan made solenoid can only be found second hand, it needs to be tested and donor cameras are not quite that easy to find anymore. There was a time when one could find socalled NOS (New Old Stock) solenoids in Japan, Akihabara. Not cheap either. Here in Europe donor DSLR bodies have usually 1 useful solenoid inside, it seems Europe was a kind of guinea-pig for testing the green one, because in almost any K100D, K200D or Kx and similar I found the white one on the diaphragm control block but a green one for the flash. K10/20D anyway have just one! So for somebody who does it as a business, it means finding the donor, buying it, disassembly, testing, offering it on ebay com: So the price seems quite reasonable to me.

Of course one can moan about it (I don't mean you!) for it once costed something like 50Cents.
A Telefunken 12AX7 was US$ 2,50 those days, but because it is one of the best ever made 12AX7's these days it is up to US$ 500 (in its ECC803s version).

Hell, I need to check my stock! I might be sitting on a goldmine!

My repair was cheap for parts ($28.00) but the labour was $180.00 plus shipping and insurance both ways ran the cost close to $300 Canadian! But happy with the result so far! SharkyCA

Thanks for all the notes. Iíve just upgraded from a K10D to the K70.

If I understand correctly, it sounds like this is a low risk issue?

And should I keep my K10D in case parts need to be harvested from there? Or is that not an option?

Indeed!

It is twice an option:
You have the solenoid if ever you'd need it
You have a very robust back-body, which anyway makes very good photos if light is reasonable. You know how to handle it, it would bring little money.
So best to keep it and every day and then use it, charge the batteries.
I still have mine and have it always in my car. In pretty battered condition it is accompanied by an as much battered FA50/1,7 (front plastic broken off, so with an stepup adapter glued on, I love this lens) a WR Kitlens and the old venerable SMC A70-210.

Thanks. I have a 50mm 1.4 with broken plastic. And I love my K10D, keeping it is an easy choice. Thanks.

Hi, I think my k-70 fail is indeed a rare failure, had I purchased it through Canadian channels it would've been covered under warranty.

Still, I love the camera!

Cheers!
