#### SSON [surplus sales of nebraska] has tons of Buss HV
fuses. The HVU-3 is what I use. [rated at 3A @ 5 kv AC]
These are 13/16" diam on the ends, and fit standard 3/4" fuse
clips. The fuse itself is 13/16" diam x 5" long. They have the
3/4" clips too... in 2 x diff styles.... I use the slightly better
ones... with the end retainers. That way, once inserted... they
CAN'T slide out. Good, cause mine are mounted vertically in
several of my many HV supplies.
;-) Worth to remember when choosing to put them vertically.
### You can still get em new... on Cooper Bussman's
website ,buried under HV fuses. The HVU series above is
sandfilled, u can also get em without the sand..... and a lower max
interupting current rating. The new ones all have ceramic bodies,
these surplus ones all have glass bodies.
Just looked on the UK web site of Cooper Bussman and found a German distributor (a mere 100 km away from where I live. Good!) - Thanks!
### The 120mm long ones available in EU should also work. I'd
place any HV fuse BEFORE the glitch R, not after.... just in case
the glitch R comes apart... and touches the chassis/metal. I
also insert a 2nd HV fuse [in one leg only on a single phase xfmr]
between xfmr sec... and diode board.
Yes, that's what I had in mind, too. Although the SKN3F20/08 diodes I use are of the more rugged type... ;-)

Thanks again!
