[time-nuts] OT - Old Hatfield 2105 Step attenuator specs

[David]

Alan, good point I'd forgotten Pascall inherited this attenuator, I've a 
vague recollection of using Hatfield ones decades ago and suspect the 
spec was similar to:
http://ijkscopes.com/PDF_image/Pascall%20PDF/AC701_AC702.pdf
RS components retailed these for many years so that may be another 
source for an older data sheet

Giuseppi, with any old attenuator its worth a DC resistance check to see 
if one of the attenuator sections has not been fried over the years. 
Should be easy enough to fix if somebody has been careless, I recall it 
being made with standard wire ended resistors, 1.8 W or something similar.

Hi agn Giuseppi that may indicate your units date from later, after the
company were acquired by Pascall
