Product Reviews
I own a Fender American Hand-Wired '64 CUSTOM PRINCETON REVERB which had some microphonic tubes.
After reviewing some possibilities I decided to completly retube with new re-issue Tung-Sol tubes (2x6V6, 3x12AX7, 1x12AT7 and 1x5AR4). This setup sounds a little warmer and more dynamic than the stock tubes in my opinion. I'm thrilled withe the results! Great service (ease of purchase and prompt shipping) from Antique Electronic Supply. Highly recommend!
I love these tubes and you guys ship fast! Thank you!!!
