I have a resistor in a Merak center channel that I'm modding. The resistor is a white long-house shaped thing with the following printed on its top: "7W5R"
Anyone make any sense of the resistor's value from 7W5R ?

There no bands on it?

No bands. I have a digital picture, but no host, so no way to post it.

Hmm.. maybe would help to see a better pic (of the whole circuit) if possible... it looks like it's glued in, but...
It looks like (hard to tell from the pic) you have a sand block resistor there - used to find them a lot in CB radios. The marking is confusing though, they'll usually be marked, say... 5W50(omega)±5% - 5 Watt, 50 Ohm give or take 5%.
Maybe if I could see the whole circuit... looks like there's an electrolytic cap behind it... other than that - it might as well be lego.
Worst case scenario... take it out of the circuit and measure it with a multimeter.

7W5R eh...
could be 7 watt resistor, 5 ohm.
Usually they have the color bands as mentioned above, or in the case of ceramics they have a number. Id have to go look at some of my notes to decode the ceramic type but color bands are easy, there are a bunch of online calculators. As BrenR suggested, if you have a DMM just set it to resistance and measure it, you can just clip the leads onto it without un soldering it, but probbly wont get an accurate reading.

Nice find chess
I forgot, when i said that the ceramic ones had a numerical code i was talking about small ceramic CAPACITORS... DOH! (yes, its been a while) I better get my stuff straight cos' im gonna be starting my AAS in electronics technoloy starting this fall.
