Looking for suggestions/help please.
Orbe has been running fine for some time then the other weekend I was showing the wife the differences between the 3 decks I have with the same record/tracks.
First 2 decks went well (Lenco GL75 & SP10) then moved on to the Orbe - straight away you could tell it was running fast to just used the 2 other decks.
Managed to get some time today to have a look and it is running at around 34.29 (+2.8%) - this is the AC version of the QC and motor.
Checked the voltages on J3 & J4 and as near as dammit at 19.5 volts which is the recommendation (when the speed selector is set to 45RPM (runs at over 46), J3 & J4 are more or less as close to 21 volts as you can get.
After much mucking around (setting the volts, higher lower etc managed to get 33.3 with them set as close to 19.5 as you can so all good.
Put everything back and the deck is running back at 34.3 again so cover off the PSU and both J3/J4 are still reading at 19.5 volts
The only other thing that has changed was around 6 months ago where I changed the belt for a "Michell" belt but the quality is average at best (the other belt was well and truly past its sell-by date !!
Any ideas what next (could the belt be causing this?
