Like the arm, bet that was great fun to make, no problems with earthing I guess. Does it work well/sound good? Nice amp, I take it is PP? I do not know much about tube gear as this is a new interest. Is the ST70 a design or an old model of amp that you have restored?

The Arm sounds Great...I found the Design here, it's a Nanook Arrow Shaft Ball Point Pen Unipivot Design....It cost no more than the time it took me to make it...The Amp is a Dynaco ST-70 that was Modded when I first bought it over 25 yrs. ago...Since then I started using KT77's in it and changed the OutPut Transformers to 60 watt Edcors...It puts out a Very Nice 35 watt/Ch. at least, and it's a Push-Pull...

Here's the ToneArm...
