Hi - I have a NZ built Fountain 10-10 10 watt ECL86 integrated amplifier. I love it
The issue is that there are 2 x ECL86 per side - in this case Telefunken - and there is a hum that follows the tubes when you swap sides.
in order to rule out component issue possibly contributing to this - I want to ensure the resistors are OK. The former owner replaced 80% of old resistors - with carbon types. But please see some of the old ones in the centre of the photo which he didnt replace - shoud these types also be replaced? There are about 10-12 of these left in the amp.
I have also recapped this amp and there are only a couple left to replace with good Panasonic types.
cheers!
