Title: Original 1964 Vibroverb Question
Post by: Planobilly on October 20, 2016, 07:09:48 pm

Hi Guys,

I did a rebuild on a Original 1964 Fender Vibroverb today. What a killer sounding amp! I had never actually even seen one before other than in photos.
This one was a blackface. As I understand they were only made in 1963 and 1964 and only around 300 were produced.

I took a look at the AA736 schematic and the AB736 schematic. I did not see a difference. Is there any difference?

Thanks,

Billy

There are quite a few differences scattered across the schematics.
