... The resistor I smoked is actually the one second one in from the right on the TOP of the picture, left picture. Looks like blk/brn/brn/silver to me from the pics. Is my eye sight gone like my memory?
Hi DM: reading colors off web-pics can be a guessing game; too many things going on ... color attributes of the camera, original lighting, piddling with the pics in pic editor applications, out to the web, back down to earth and then how different monitors render the same colors differently ... and then there's the part about eyesight.
If you are certain about which resistor is smoked ... then I don't think it was black / brown / brown ... black is never used as the first color. What follows is part certainty and part guesswork ... I'm relying on the same funky colors too; with that out of the way, here we go.
You said '2nd in from the top'; to me, that's R #8 below. If so, that's the cathode resistor for the front / triode half of the 6BM8 ... the driver half. If that's the triode cathode resistor, it would be coded red (2) / red (2) / red (times 100) ... 22 X 100 = 2,200 = 2.2K.
Let's try this: 'You're wrong Juan ... you're way off ... ' Okay ... I'm posting while drinking but if it's really brown / brown in position #s 2 and 3 (we don't care about silver or gold [we do ... but not in this case, those #s are for quality and tolerance] but, I'm wrong/you're right it's brown and brown .. that would mean that the second # is a '1' multiplied by 10 leaving the resistor's possible values as 110, 210, 310, 410, 510, and so on ... but there are no resistors on the circuit board - other than the 470 ohm - that are less than 1000 ohms. I'm not saying I'm right, I'm saying the smoked resistor can't be black / brown / brown.
Get to know this; pics like this are all over the web ... print this, print another one ... but print one.
If you don't have a meter, get one and practice with it; you can also improve the chances of my guess being right through a process of elimination .. which is all I've done here. I like to use a continuity tester; if all I want to know is which end is grounded, I can clip a lead to the chassis and find the ground end faster than I can read 0 resistance. If #8 is the 2.2K and even if it's ruined, it'll read 0 resistance between one end and ground. Anyway, #8 at 2.2K ... it's just a guess. Good luck with the amp.
