[time-nuts] Replacement A9 boards for the HP 5065A

[Charles Steinmetz]

Interesting.  I'm inclined to say I stand corrected, BUT:  (i) as Mark 
noted, the datasheet link points to the datasheet for Vishay FC Series 
HF thin-film resistors [which are really excellent low-reactance T/F 
resistors, if you need any]; (ii) I cannot find any reference to PC caps 
on the Vishay/BC web site; and (iii) other distributors do not list this 
cap (or any Vishay/BC PC caps, for that matter).

I did discover Electronic Concepts (ECI) (https://www.ecicaps.com/), who 
claim to make their own PC film and do seem to supply three series of PC 
caps.  They seem mainly to make them to order, but they have small 
quantities of some parts in stock.  Prices are by quotation, so I don't 
know what they charge.  I assume they are pretty pricey, and if they run 
out of an in-stock cap there may be a minimum order to get more.

So, I do stand corrected.

All that said, PP and PPS are the best choices for the A9 integrator 
project.

Best regards,

Charles
