    Carver power switch doesn't hold in on position

    Holy-Moley, that's in terrific condition. I've attempted to win one on the auction site but, I always seem to be under-bid. I feel I'd rather have the improved effects the 'T' offers as compared to the regular C-4000 that I own. Enjoy that one it looks very clean. FM

    Carver power switch doesn't hold in on position

    The power switch will rarely if ever hold itself in the 'on' position so, I by-pass it. I'm using a power-strip. It's difficult to show it as I haven't unmounted it because the pre-amp has every input and output being utilized: 2 tape decks, 3 turntables, 2 SUT's, a tuner and 2 CD's. I would...

    Carver power switch doesn't hold in on position

    10-8-18 Anyone know the correct part number for a AC power switch for the Carver 4000 pre-amp? I see what I believe is an appropriate switch here: https://www.ebay.com/itm/Alps-SDU3P-Power-Switch-TV-3-NAD-Realistic-Marantz-Concept-16-5-Sanyo-Receiver/282652002874 Possible Part number is: Alps...

    C-4000 Pre-Amp

    2-26-18 Gentlemen, that’s exactly what has happened. I played with the switch till it held/stuck in the ‘on’ position and I’m using a small old ‘Isobar’ strip to power the power distribution/conditioner on only. I have connected full-time a power distribution/conditioner box that has a 5 second...

    C-4000 Pre-Amp

    "" """ @ WOPL Sniffer, You are describing exactly what the switch is doing. It definitely feels and appears that the switch is simply not grabbing or catching into the on position. So, either it's a worn minor part of the mechanism. My experience would let me remove it and slot...

    C-4000 Pre-Amp

    Thank you "grapplesaw", you've been very helpful. I just now purchased one. I'm thinking I'd have to remove the bottom cover of the C4000 to get to it. Do you think I can use the original capacitor as finding just one or two is probably not possible except for maybe ratshack and who knows of...

    C-4000 Pre-Amp

    Hi grapplesaw, I really can't see how many lugs on in the foto but, I believe there's two or so on each side. I've also read that simply using the other side if one side's contacts are burnt? It's a hassel not having a single button. I've located some that look close on Mouser...

    C-4000 Pre-Amp

    Does any one know of the part number or part number equivalent for the AC On-Off push-in switch to the Carver C-4000 pre-amplifier? The one I have doesn't catch in the 'on' position any longer and is always problem to use. Is it PN NE1839EE ? Anyone in or near...

    To All of You With vintage Hi-Fi Stuff

    To all you lovers and curators of the classic Phase Linear craziness. You are not totally out of any loop in the world of music and the equipment that reproduces it. Vintage equipment has a purpose and a meaning, is it 'grass-roots' more than just a hobby? Does it have a stronger reason for...

    Afraid of the heat..................

    9-13-16 So, was an answer put forth or did I miss something? At this point it's still not clear to me with everything concerning my apparent heat problem. Was I over-reacting, maybe worrying too much? Was I supposed to bring the ‘bo’ and brew to this party? No one told me to. Should I just...

    Afraid of the heat..................

    FM's response: 9-12-16 I thank you for your response, I entertain all opinions and advice from just about any one in the ‘know’. But, with all due respects, surely you jest. Are you correct in your quote of said manual? I’ve checked the both manuals and either you’ve made a mistake or you are...

    Afraid of the heat..................

    9-12-16 Many thanks to all who have responded thus far. I’m still curious if anyone has measured temperatures of their gear as I feel this is a valid point, especially in light of upgrading to another level, or by simply keeping our amps performing up to par. I usually place a digital...

    Afraid of the heat..................

    Just to be clear. He stated that 'I' should not attempt to touch the bias for any reason. Not that I have the knowledge or equipment to start monkeying-around with anything. It was stated that: “”Current limiting feedback loop caps replaced on both channels (47uF Nichicon PW)...

    Afraid of the heat..................

    Thanks for responding to my post laatsch55. When I spoke with the tech/seller he discussed oscillation not to be evident after he put it together and tested it. In light of any possible mishaps the speakers are fused with fast-blow 4 amp fuses. My other speakers utilize their factory FNM2 fuses...

    Afraid of the heat..................

    9-11-16 I recently purchased a PL-700 Series II because I wanted to upgrade the amps driving my vintage AR-9 (4 ohm)speakers. I had a bi-amp setup using two PL-400 Series I. But, both of these amps seemed to run out of steam at high volume listening levels, so I was seeking more. The new...

    'Fear of Flying Into WOPL Territory'

    7-30-16 Gees, I guest Perry and “Northwinds†have made it clear to me what goes into a ‘rebuild’. My questions have been answered. ‘Decision-Mode’ may have to be put into affect right now? To “FredR’s†reply; I caught that amp in my travels also. The curious thing the...
