any inmate having problems w/ theyre sp 11? mine has a problem w/ the impedance switch. it seems the gain markedly goes down when im using the phono section when the unit has just been turned on after a proper warm up.what i discovered was when i move the impedance switch back & forth from 47k to 10 ohms the gain goes back to its normal level.any suggestions? can i spray contact cleaner to the impedance switch. i did not have this problem in my sp 10 mk2 w/c has serve me well for the past 15 years.
