I have been running a Sugden A21a with Celestion Ditton 66's and a Sugden CD21. But have now bought an MF A120 intergrated amp, and found to my amazement that it works better with these speakers than the Sugden A21a. I would like to service the A120 and maybe, upgrade it further. But cannot find a copy of the circuit diagram anywhere. I am willing to pay for this if someone can help me.
Thanks
Pete
