Hi folks

Got the chassis out to start the work needed on this and just out of curiosity the only number I can find on the chassis is AF0911 I have a feeling this is a serial number. Thanks for the link Trevor but when I looked at the information, the valve bases are not octal they are of the 6f series, only v4 of the A353 model has the octal base. In both circuit diagrams the smoothing cap appears to a 16+16uF but as the A358 has a AZ31 the max capacitance for the reservoir is 60Uf so I am considering putting a 50+50uF in.
