EICO Tube Amp HF 14...Transformer question

I just purchased these vintage Mono Blocks .

Upon checking the insides I noticed that one transformer had shilac colored fluid....possibly leaking on its bottom.

Is this indicative of a problem ?....or is this normal ?

Also:...there is no fuse value written . Does anyone know the correct fuse value.?

Thank you

Are you sure the liquid is coming from a transformer? It's more likely a leaking capacitor. You need to power up old units slowly with a variac. Best to connect speakers when powered up. Any photos?
