When I switch the unit on, the LHS works fine. The RHS channel let out a few muffled grumbling sounds before turning silent. Repeating the procedure produced the same results. I then tried various settings on the balance control as well as turning the volume up and down. There were extremely low squeaks from the RHS output.
Thus I suspect the issue was similar to that of my Quad 33 (post in the past) - due to oxidation of the contact points on one of the boards of the Leak. The internal setup of the integrated Leaks (Stereo series and Delta series) are all similar.
Please power off the unit and disconnect the power before proceeding any further.

Since my unit had issues with only the RHS channel, I concentrated on the two boards with "R" on the top of the grey plastic bar. To access the boards, you need to gently lift the plastic bar (which is held down by a gentle spring).
I pulled only the "R" boards from the motherboard and sprayed a little contact cleaner into the board cradle of the motherboard. Then returned the boards to their cradle and return the grey plastic strip onto it's grooves - the way I found them.
Left the unit alone for about 30min or so before restoring all the connections ... all's well again!😄
So before you head out to visit the repair shop for a similar issue, give the above a go 1st.😉
