Hi there,
Recently I bought a P300 with the multiwave and performed a recap of the bigger caps, since the originals were bulged already.
Something I noticed is that the output voltage increases with some of the multiwave settings.
Ig you set the voltage to, lets say, 110V, when you “scroll” thru the settings the output voltage rises to 113, 114 and even 120 then start decreasing again.
The display continuously shows 110 but the output varies.
Is it “normal” or my unit may have some problem ?
Nobody else noted that ?
Could the owners verify, please ?
My guess is most P300 are well beyond their expected lifespan. I had two original versions without multiwave so no comments. Considering the P300 age I’d be looking to move on to something more “current”. Pun intended.
MultiWave does have different voltages because of the way it produces the sinewave. This is normal.
Sounds like you’re good to go. I watched your video where you recapped the P300. Good job, you recycled and saved a piece of history from winding up in the dump.
I really like the styling of the older power plant.
Thanks Paul. Great product still. Just love the brand and what it represents.
No, it´s not. Mine, at least, still works flawlessly and after a recap is ready for the next 20+ years of service.
Both of mine made it just past 3 years. I was an early adopter for the PSA Power Plants. There were issues with early units that could not properly disipate the accumulated heat. Caps failed catastrophically in each. There was additional component failure cause dby the heat as well. IIRC at some point PSA offered (1) multi-wave later, and then a fan cooling retrofit kit for the P300.
I pre-ordered and got one of the first. Mine worked flawlessly about 8 years and then the power switch went south. I still have it. . . .
I’ve had mine for about as long. Mine died after about 8 years or so as well. I sent it to Cullen Circuits and they rebuilt it with some modifications. I later added a new fan control circuit when the original said sayonara. It still works fine but I haven’t had any use for it for many years. I think it would still be very useful for someone who needs tightly regulated and adjustable voltage for their turntable motor.
Adding a fan seemed to be a necessary step. Both of mine saw light use supplying a CD transport, DAC and tube preamplifier. I had two, each dedicated to seperate listening systems. At one point I had intended to rebuild them, but my interest waned and into the dumpster they went.
I just added a second fan to mine. A very silent Noctua.
Now one sucks the air in and the other blows it out.
How erotic… LOL
