Hi sds2000,

I was also unable to find a schematic on web for my Rev 7.1 unit.
That's because M.E. will not release it. He wants a fortune for these poorly executed manuals too. Shame on him.

As long as you have it open you should replace the volume and balance pots.
Well, they normally clean up very nicely. If you were thinking of replacing them you should have used a nicer Alps or Nobel pot.

This was drawn too many years ago. No sure why R5 has two values. The correct value is probably 4M and 1M5 is the ideal RIAA value. The grid-leak tube lowers the input impedance.

Hi.

I bought my SA-7 at a car boot sale for 50 - bargain !!
The guy had just upgraded to Krells.

The only problem I had was the switching arrangement - SW1/2 - the phono stage is always in circuit.

I sourced a 3-way ON-ON-ON from RS Components and rewired it.

I sold the SA-7 for 275 when I went CD only. (almost my bestbuy at boot sales - the complete stereo quad 22/II/FM2/AM2 for 25 will take some beating)

For those interested, I have posted the circuit here :-
