New amplifiers, interesting repairs and other musings
I had a nice old tweed Fender 5d3 Deluxe on the bench yesterday for an overhaul. I had to replace all the electrolytic caps, installed a grounded cord, a new pair of EH 6v6, and a general degunking of all the controls etc. I also noticed that the output transformer was a 60's era replacement and had never been wired correctly. This transformer has various ways to connect it and the way they had done it only reflected a primary impedance of 4k when the proper spec is 8k. I was able to change the secondary to double that and now the amp is operating perfectly and sounds great. It was only making 6 watts on the bench and sounded super thin before I changed the transformer connections but now it sounds perfect!
