Hi, Attached is a schematic of the changes made to the stock 10811 for use in the HP 5071A. Also while I recently had two of them opened I noticed wavy lockwashers under the nut attaching the tuning capacitor. If you have ever had to open one up to retighten this nut you would wish all of them had the lockwasher! Cheers, Corby

“Wavy lockwashers” are actually a form of spring washer known as a — wait for it — “wave washer”. General design considerations and information here. <https://www.wclco.com/spring-washers/spring-washers-general-description/> Grainger and many others carry stock. — Eric > On 2018 Jan 16, at 12:19 , <cdelect@juno.com> <cdelect@juno.com> wrote: > > Hi, > > Attached is a schematic of the changes made to the stock 10811 for use in > the HP 5071A. > > Also while I recently had two of them opened I noticed wavy lockwashers > under the nut attaching the tuning capacitor.
