Hi Guys,
Sorry for reopening this thread. If necessary, start a new thread.
I have a number of Yamaha power amps for a while now. One P2100 and two P2200's. They work perfectly and I have never problems with them. There mounted in a big flightcase with active an self made active cooling system.
Well now my question. One of my P2200 had XLR as speaker outputs. Someone in the past built them in. Because the hole is already there, I replace them with speakon. Nothing difficult. But, opening the amp was giving me a new view over all of the parts with a layer of dirt on them. And, I saw that the voltage switch is on 220V. Shouldn't it be on 240V? The AC supply in The Netherlands is around 230V.
So there are two questions.
1. Should I remove the dirt in the amp even if its working perfectly? There is no hum or anything. Just working perfectly.
2. Should I set the voltage selector to 240V?
Thanks for reading my post!
Robert.
AWESOME amps.
And love the meters
I can always use another one ( hint hint)
Now that the cover is removed, I suggest getting rid of that dust. I like starting with a vacuum cleaner and a brush. That shall get rid of most of the dust, then finish off with some compressed air.
I have three P2200, two PC2002 and one PC1002. I noticed that the P2200 have burnt bulbs. I will look into changing them with same size LEDs, most likely 12v. I will remove a dead bulb from one of my for-parts P2200 and look into the supplier below

BTW If anybody has a big round power supply for a P2200, please let me know ;-)

Hi Robert, I know a guy who knows a lot about the professional amps from Yamaha, especially the P2200 (BTW, I also had one -loved it).
He also does some mods to make them sound better.
You can find him on Audiofreaks(dot)nl forum by the name "Jerry". He lives in Tilburg.
Ah, oke nice! Thanks for the advice. I'm a member of Audiofreaks so I will sent him a message.
All the voltages are defined as +/- 10 %. In Europe by now we have 230 Volts +/- 10 %.
If you select 220 Volts at the amp and feed it with more (230 Volts) then some components in the amp may get overtaxed with too high voltage.
If you select 240 Volts at the amp and feed it with less (230 Volts) then the amp will clip sooner, but nothing will break.
If the amp has a regulated power supply (I bet it doesn't) then with 240 Volts selected there may be insufficient regulator reserve.
Select 240 Volts.

Thanks!
The amps are now switch t to 240V. Last Friday had a wedding party. Setup was two Yamaha P2200 and two Yamaha F1030 crossovers. Speakers where Altec 8254, but with 3156's in it for the bass, for MF and HF I used two Tannoy Puma's (first series). Sound was great. People came to me because they were not familiar with such a sound on party's. Also did the Lights with 8 Par 64 and 8 Par 56 and some special effects.
Nice vintage PA gear
I wonder how do the F1030's sound, it looks like they use trafo's on the XLR outputs.
