Long Slide Speed Equalisation Switch for Revox A77, B77 & PR99
These slide switches are pretty vulnerable items. Usually if there is no mechanical damage they can be carefully cleaned with non residue switch contact cleaner and a cotton bud [never sprayed!!]. However sometimes some of the leaves are bent or badly tarnished resulting in spurious speed selection, incorrect equalisation and puzzling poor performance during set up.
Two types are available for the A77 and B77/PR99 - they look the same but are different on closer examination with different number and position of contacts / leaves.
STOP PRESS ANNOUNCEMENT: Sorry but we will no longer supply these switches as spare parts only. The limited stock we have are now reserved for past customers or those customers who commit to a proper complete job and purchase a full electronic or full monty overhaul kit.
Also, B77 no longer available but we will supply A77 version which can be modified together with your old one for a B77 / PR99
