Fuses in the 3 speed SME PSU


I have a model 20/2 table serial # 1173 and wish to upgrade the PSU with Hi-Fi Tuning fuses. There are 3 in the unit and my question is, which of the 3 are most critical to the performance of the unit as I cannot afford to upgrade all at this stage.

You’re close, Uber, very close. He was winding you up. Like a top. I can always count on you. 🤗

re your idea of masking tape on fuses.... I considered this, but was concerned about long term drying of the adhesive. I used Teflon plumbers tape, tightly wrapped around the glass. Nice uptick in performance.

@richardkrebs You know, you have a point. I've used PTFE tape on the Linn Ittok arm tube many years ago. I'll give it a try. Thanks!
Some cool things you can do with fuses. This is very hush hush 🤫 so use at your own discretion. Color the Contact portion of the end caps purple/violet with Sharpie marker. Place fuse(s) in home freezer for 48 hours. Remove and let slow thaw in refrigerator for two hours, reinsert fuse. Try each fuse both ways obviously, one fuse at a time, even if stock fuse.
