Your amp is fine.
The "number" on the pots is only a reference number, does not mean a given power output.

I agree, it's just the way the amp was designed.

So your saying that even though the amp seems to turned half way up it's no reference to the power of the amp?

I have a Fender Pro 185. Two twelves, 185 watts and a reputation for peeling paint if you don't watch the volume. Channel two, the dirty side is loud and easily keeps up with the band with master on 3 and drive at about 5. The clean side sounds good but I have to keep it at 5, seems to me thats higher than it should be. I have replaced the "bass" pot on this channel, the shaft was snapped off, and I lubed/cleaned the rest of the pots. What are probable causes for lowered volume? On a tube amp I would look at the power tubes but obviously thats not the case here. Everything inside the amp looked good, clean and where it should be. Any ideas?

Does it come out of the joint with age? I've never seen concentrations as numerous as this.

Found one from a guy named Darren Riley in North Carolina, Fender has none. Still looking for the master volume pot, suspect I'll have to substitute something thats close.

While removing one of the pots on my Fender Pro 185 I noticed that many of the solder joints had a reddish deposit on them, very soft and easily brushed away, is this the rosin in the solder?

Think I've found the pot I need, the value is 50K15A and the Fender part # is 0027940000, had fun getting it out but feel I'm on my way to repairing this old beast. The problem with lack of volume on the clean side remains, the value is 50K30C and as yet the part # I came up with is unconfirmed by Fender.I'm hoping that just cleaning out the pots will help

Interesting! I had wondered about "the bag" that encloses some reverb tanks. I have just acquired a Pro 185 and really like it. Short of a broken pot it seems to have no problems, yet. For late eighties solid state it sounds, well.. great!

I have not taken it apart yet but if it's like the Fender Stage Lead amp I had, also from the late eighties, the pots are of the "snap in" variety. While I could match up the values and post size these pots rely on the chassis for a strong mounting and connection. I may yet be forced to take it to a shop, but at least I know a good one nearby.

I recently acquired a Fender Pro 185, the red knob version no less. The band and I think it actually sounds better than my similar all tube amp, but it has two problems. The primary one is that the knob for bass on the clean side is broken off at the shaft. Needless to say Fender no longer supplies the pot, does anyone have a source for this? Second problem is that the clean side seems to not have alot of power, in an amp famed for being super loud I have to put it up to 5 to keep up with a not too loud electronic drum set. Having said that the distortion side can definitely peel paint. Any ideas?

Hi, first post here. Have an old (1986) solid state Fender Stage Lead in need of a new pot for the treble on the amps distortion side. I have been told Fender no longer stocks this pot( part# might be 0028576000). I would like to order one from Mouser but am not sure of the pots values. Onlt writing on the pot is 15c-50k, and upside down U (sigma?) then jp. Its a D solid D shaft one half inch long. Shaft was pulled out of the backing plate, I pushed it in and reassembled it but I would prefer a new one. Thanks!
