Farnell TSV70 Mk2 restoration

[reddish75]

So, Father Christmas brought me two of these with apparent faults as which I've yet to discover, so I thought I'd refer them so I wouldn't have to bother with them in that way for a few years,

I thought I'd ask the knowledgeable folk on here what to look for before switching on, best way to switch on (probably for the first time in a few years)?

It seems like I'll have questions lots of questions if anyone's willing to help?

In the meantime I've wrestled the covers off one and measured the bigger caps which seem to mostly be ok, enjoy some photos of the inside.

No. 1 measure:
Before switching on you must unconditionally replace that
cracked input filter/spike suppression capacitor as in pic No. 6.
And then look to see if there are any more of this kind which
urgently need to be replaced.

No.2 measure:
I'd also have a look at all other capacitors.

No.3 measure:
And also check all metal parts to ensure that they are all connected
via a low resistance to earth.

Any time you see that style of class X cap swap it, with those it is not so much a case of if but when.
Awful things, and I think there are two more in photo 3.

I would suggest that a 60W incandescent light bulb in series with the mains at first switch on is a good idea, makes something very wrong obvious.

Good supplies.
