J!m, I feel the same exact way -- there is a sense of satisfaction when you fix something in order to get the total "price per use" lower than it was when previously abandoned...
BTW, I liked your mixed metaphor, and got to wondering if I'd ever heard/read it before?
As it turns out, currently there is exactly '1' listing for that phrase on google. (!)
Revel in your unique train of thought! :0)

Derailed train of thought unfortunately. But, it doesn’t stop.
Started resurrection of another scrap heap today. Pioneer SX-880 that looks as if it was the main system at the local sewerage treatment plant. Knobs we’re in ultrasonic alcohol for two hours and are still nasty. They’re soaking (without Sonics) overnight now.

The HP 6228 Dual tracking power supply ($37 + shipping/tax = $112.47 to the door) arrived from Arizona today. Here's what I received:
(0-50vdc, 1 amp x 2 channels)
But wait, there's more! Shortly after I found a slightly different HP 62xx series power supply on offer -- a 6227, which offers a 0-25vdc, 2 amp output x 2. A little less voltage, but a little more grunt, looked like a good fit for what I have in mind down the road. A little more spendy at the asking price of ~$120, (but the seller knocked a little off) the shipping was only $36, and of course the 8% NY state tax = $146.90 to the door.) It was so clean, looked like somebody owned it at home vs. just being used in a manufacturing production environment by employees.
And what tipped me over the edge was the very neat, very cool DYMO label on it. So here is my lab-to-be's 2nd power supply:
(0-25vdc, 2 amp x 2 channels)
Total damage to the piggy bank for both power supplies is $259.37.
IMHO, this compares favorably to this clean (single) HP power supply on eBay today, listed for $395.00 + shipping:
Of course we'll see if I'm still smiling after I rummage through both units & see what it's going to take to bring them back to trustworthy status. :0)
Happy New Year to all my fellow audio enthusiasts here in the Phoenix PL forum!
Cheers -

OK, another small step for the lab - the Simpson 260 came in from TX.
Note: My focus was on the meter & leads, the leather case was a bonus - even though it had 3 silver-colored smudges/fingerprints on it...a don't-care on my end. More importantly to me was the photos of the internals showing the board & all components were in mint condition.
As it turned out, a little bit of old-school KIWI saddle soap on a moistened washcloth removed the markings & brought the leather case back to new condition. Better yet, check out the pink poly bubble wrap w/note + clear top wrap that the seller (" n5oe ") employed. This was on top of all the box filled with the shipping peanuts. Definitely an A+ for protective shipping.
Beauty shot --
Here's the meter in the leather case:
And here is how the meter will look whenever it's not in active use:
Even though I have digital voltmeters & use them by default, for some adjustments is just a lot easier to tune to a peak (or null) by watching a meter swing vs. watching the numbers on a DVM. And there's always the benefit of being able to do a quick cross-check when you are getting counter-intuitive results. Sometimes, you need something with the ability to swing...

Lee, it has that NOS (New Old Stock) look & feel to it. It's too nice to bang around in the garage with it...no worries, I am at least 2 deep in 'looks bad, works good' type meters already in use out there. :0) It's nice when you don't have to drag out the good stuff in order to troubleshoot the 'no headlight' writeup on the snowblower. :0)
George S, just watching the meter swing & zeroizing it brings back a flood of memories...all the way back to Basic Electronics class in high school. (I have to admit that the purchase was part practicality, and part nostalgia. Just like I'd rather ride around in a '55 Thunderbird than a '05 S2000.)
Not to mention that it will be a nice Easter Egg in the background with the test subject in the foreground. It really is a classic, and for a certain portion of the crowd it will help to give the shot/story some visual cred. :0)

Lee, you saw how I wrote up how much better I felt undoing the scratches on the dust cover of my old Dual turntable. Even if you blew an etch you can usually put a lasting 'field fix' on it with a piece of wire bridging the damage & soldered on both ends.
Some things can't be quantified in terms of a normal business transaction...fixing Dad's old Simpson is at a whole 'nuther level. I say go for it -- it will feel much better than it has any right to when you bring it back to life! :0)
