Hey all, Just bought a 1970 Fender Super Reverb and I thought I'd get a few opinions from the crowd. The serial number would make it a 1971 (A50020) but the transformers are all 1970 based on their numbers (606047 on one, can't remember the other two off the top of my head) So do I have a 1970 or a '71? Also the speakers are the CTS Alnicos (137 6949) and they sound amazing...I absolutely LOVE the tone I'm getting BUT...would you keep the stock speakers in there or preserve the speakers, pull them out and put in good replacements? I'm kinda torn here...love the tone but want to keep it all original and not risk blowing them out as this will be my main amp for gigs now. Just looking for opinions and if you would replace them. I'd love some suggestions for which new speakers sound great in the SF Super Reverbs as well...thanks for your opinions.
