Fender 112 SE hum issue, also Inductor coil part replacement help needed

[rocknroller]

Was working on this fender amp that has a hum issue regardless of channel selected, all controls zero. Even occurs when power amp in patched into. Someone had previously repaired as well. Big resistor burn at R76 (47 ohms 2watt) was previously replaced with a vintage resistor. Quick google search seems these resistors burning up are somewhat a common problem, but I've yet to find a source cause identified. Also R82 (10 ohm) had been replace with a vintage 8 ohm or something. Plan to replace that for sure and back to spec value. When I push on the large filter caps, the hum ceased so I figured bad solder joint so touched them and others around them up. In the process of touching up the coil joints, the 2.5uh coil fell out. Only one side apparently connected so either I broke the inductor coil lead at some point or it was already broken and pushing on the filter cap flexed the board enough to make contact with the broken end of the lead temporarily. Either way, the lead is clearly snapped off one end. Problem is, there's no other information about it. Quick ebay check and no one selling anything like it. Any ideas on where to find a replacement and what the actual replacement is? I assume their are other relevant parameters other then just the uh value. Pic attached. Just under 1 inch in height, about 5/8th in width.
Alternatively - can I just solder attach a new lead to it or with the properties be so radically different it just won't work?



Secondary question - C49 (right next to R75/76) is a large brown drop .1uf cap. Actually measures .15uf. Concern? I have a 400v .1uf orange drop that I could put in that is much closer (actually measures 1.2) Just not clear if that cap is contributing to the previous resistor burn or not? Also what the whole purpose of that part of the circuit is for?

Just carefully unwind a small portion of that coil, scrape the end of the wire and solder it back in. It won't change the value enough to worry about. The coil and resistor are in parallel at the output of the amp. Since the coil was broken, all of the output current went through the resistor. Once you repair and resolder the coil, the resistor will hold.
