Change all those cans or the 3 caps in each before touching alignment ,which if untouched is possibly fine.

You mean the cans with the cores in?

No,they are slim cans with caps in them.To do it right the need "re stuffing" with small new caps or leave in place and fit the replacements under the chassis.Of course disconnecting the old ones first.

These are the cans. If you don't want to re-stuff them just cut the leads and replace with polypropylene caps under the chassis (one at a time to avoid mistakes!).

I have done those, however, under a small screening plate, found a metalised 0.001uf and a black hunts 0.25uf so waiting for an order come come Friday run out of things, so going to restring the dial cord on a HMV 1115, been doing for a while. Thank you Keith.
