Sorry, I don't much about these "parts" and I "hope" I have them listed correctly as to what they are. -- IF I'm wrong, KINDLY message me and I can correct the listing IF there is NO bid on them ---- You are BUYING this "VOLTAGE REGULATOR" part  or ?? -- Part Number STK 6972 -- "Probably" made in Japan by Sanyo or Mitsushita -- it is VINTAGE and UNUSED, OLD STOCK but has "glue" residue from envelope they were stored in for years!! -- also NOTE that the "PINS" are quite delicate and may need a bit of straighten out --  great for EXPERIMENTAL builders -- I HAVE many MORE "LOTS" of "ELECTRONIC COMPONENTS" listed and YES, I do combine and re-figure shipping costs BUT you MUST "request" and "WAIT" for an invoice "BEFORE" you pay!!!!!! *********************************************************************************************************** READ the STORY about these PARTS: ....these all came from my friends who ran an appliance repair store until health-issues forced them to close about 15 YEARS ago (they have been in STORAGE ever since) -- SORRY, there is NO GUARANTEES and NO RETURNS on these vintage parts -- they REPAIRED mostly Radios, TVs, Microwaves and Air Conditioners -- eBay NOW collects and pays YOUR State Sales Tax (IF applicable)    -- *********************** WHAT YOU SEE IN THE PICTURE IS WHAT YOU GET (as SPECIFIED in DESCRIPTION)!! ++++++++ ******* Please see our OTHER AUCTIONS for MANY other "LOTS" of "SMALL" Electronic Components" and other UNIQUE and UNUSUAL ITEMS and combine to save on postage. **** THANK YOU!! >>>>>>>>>>>>>>>>>>>>> Please ASK all questions prior to bidding as all sales are final My "handling" amounts to about $2 to $4.00 on harder to pack items, which helps defray the cost of packing peanuts and bubble wrap. LASTLY, the MAJORITY of the items I sell are either ANTIQUES or USED MERCHANDISE, do not EXPECT antiques or used merchandise to be "out-of-the-box" brand new and perfect items. If I say they are new and perfect, they are!! Otherwise, they are USED ANTIQUES or USED merchandise!! Sorry, I gotta say that for those "few" eBayers who don't know what USED items are. THANK YOU! 012423/DSC09382-98(1)
