Hello friends this is AudioLover again! This time I'd like to share my modified Marantz7 circuit design using 6SN7 and 6SL7, but still can use ECC83. This design is with an output protection using DB3. Attached with images and schematics. Welcome for your comments!
My very first handmade passive preamp!
Lots of fun to make it successfully amplifying and tuning sound quality in thick bass or accurate positioning :D Hope to share with all of you.
