Revox A77 VU meters


$380.00 AUD

A77 VU METERS for both the Mk1/2 and Mk3/4. New manufactured. 

Many original A77 VU meters have a sticky needles or are just useless as the internal glue holding the movement dries up and crumbles. 

 These meters are made to better than original specification and the meter movement is NOT glued in place like the originals. They are slightly different cosmetically. We now only sell meters per pair as there is a slight difference between old and new and customers have suggested per pair is better.

The meters mechanical dimensions and fixing are almost the same as the original and they fit in place with minimal adjustment / modification. However they are mechanically slightly different. The electrical specifications are identical. The slight differences are mainly cosmetic, which only if you really look closely, can one spot the differences between the original and new meters. The older meter has a slight edge lip which the new ones do not have. Initially it looks like they might not locate in top panel but they do fit in OK. Perhaps if you only want to replace a single meter then this may be a slight issue but you have  a look at the comparison photos in this listing and decide for yourself. For discerning enthusiasts,  we would suggest that the meters are replaced in pairs if this worries you.  We have had some customers file the rectangular cut out in the top panel slightly and they report the meters locate and fit better. 

As with all small meters and the originals, there are no needle zero setting adjustments. Another rather irrelevant characteristic is that exact zero is not marked and due to manufacturing tolerances the exact 'zero' rest position of the needle is very slightly variable in the region of the lower end of the scale. This is not important nor material in terms of the functionality and accuracy of the meter.  However we do match up pairs so the needles sit at visually similar 'zero' positions.
