Ok, so i'm restoring my WEM Dominator mkIII valve amp and i've come accross this wierd dark blue component labelled 'ARCOL V7 100R' which turns out to be a 7 watt Vitreous Enamelled resistor, presumably wirewound at that wattage.
What i'm wondering is, is it actually meant to be bulging in that disturbing manner? I think that dried brown goop around it is ancient glue to hold what appear to be insualtors in place but i'm not 100% sure, it could be something leaking although i wouldn't have thought there would be anything to leak from a resistor.
It measures at 100 ohms so it appears to be working alright for now and it has been there for about 40 years, but i'm a bit wary of a catostrophic failure.
While i'm at it, does anyone recognise the logo on those blue electrotytics? I'm just trying to work out how old they are. the smaller 47uF one is obviously a replacement as its meant to be 50uF on the schematic so i'm assuming that the big one is as well but for all i know they were replaced 20 years ago. It looks like GIE to me but i can't find any manufacturers under that name.
sorry the photots are a bit shit, i had to take them on my phone
