USED Nortronics PRB2H12K 2 Track Stereo 1/4in Record Head Scully Mount

Description

I'm starting to work through a quantity of mostly 1/4 in new tape heads, from Ampex, Nortronics and Michigan Magnetics. I'm checking them carefully and identifying them on manufacturer's specs so that you can be confident about what you are buying. If you need more data, please ask. I'll provide anything I can short of mounting the head on a deck and running it.
This listing is for a used Nortronics PRB2H12K  2 Track Stereo 1/4in Play / Reproduce Head. I measured
2700/3150 Ohms impedance, 448/510 mH inductance and 410 Ohms DC resistance. Inductance is about 65% of the published value, indicating plenty of life will be left after relapping.
This is from the Professional series with extended low frequency response down to 20 Hz.
The Nortronics head part numbers need some explanation. The company used 4 digit model numbers and long OEM part numbers for the same heads. Their documentation shows the correspondence between the two identifications. If you are curious, they are available on the JRF Magnetics web site. I have been unable to track down the 4 digit equivalent for this head. If you can help, please let me know.
I'm providing you the choice of First Class or Priority Mail shipping and if you want multiple heads, contact me before purchase and I'll do the best I can for you on price.
Check out my feedback for all sorts of quality items and bid with confidence.
Shipping quoted is for US lower 48 and anywhere else served by USPS Mail at domestic rates. Other US territories including US Military, please check for shipping before bidding. I ship internationally only via ebay Global Shipping
Thank you for looking
COLORADO SALES TAX CHANGE 1st December 2018.
As of this date, as a Colorado-based business, I am required to charge sales tax based on your location in Colorado rather than my location. Based on my in-state sales volume, the way I am going to do this is set a flat rate of 9% and refund the difference BEFORE I SHIP. As I'm human (I hope), I will forget occasionally, so please remind me if necessary. If you are in a location where the sales tax is above 9% and below 10%, I will absorb that difference. If your location is charging 10% or more, I will send a message requesting payment of the difference by Paypal. I hope that this will be a short term situation as ebay is progressively automating sales tax collection state by state.
