    Nikko Beta 30 relay

    Hi I've read a few threads on this: the relay on my Nikko Beta 30 Pre amp is acting up and cutting out the audio haphazardly. When I tap on the relay with the handle of my screw driver, thump and the audio clears up. I sprayed it and it got better but still cuts out and needs replacing. What...

    A not-so-original V1 McIntosh C20 preamp and the quest for a baseline of "factory spec"

    Well, I got it Friday and spent the weekend cleaning out 50 years or so of crud with isopropyl rubbing alcohol, cotton balls, q-tips and electronics cleaner. Here are two samples of before the scrub down, complete with crusted cables from decades of buildup... And here's what the inside...

    Preamp outlets in vintage equipment or powerstrip?

    Hi! I've got a really nice early model C20 preamp en route, and was wandering if anybody uses the preamp outlets for tuners/amps/phono, or if those outlets are no longer best for use. I'm used to running power strips/conditioners, myself, but if older equipment like my MR67 and restored Garrard...

    2245 Preamp Recap Screwup - Help

    I have a feeling there's many answers to this, but are there any common mistakes made when re-capping the P400 preamp board in the 2245..?? It was the LAST board on this rebuild and now I'm only getting the right channel for output. The amp was working fine yesterday. I've used it for a...

    Advice on an MM phono pre

    Hello, first post in a very long time. I recently upgraded my integrated amp from a Marantz PM5004 to a Classe CAP 151 (huge leap), which doesn't have an integrated phono pre, and I'm looking for some advice on what to get in the $300 range. Some options I've been looking at are the Schiit Mani...

    Looking for cheap tube preamp with tone controls

    Hi all, I currently have a SMSL SA-98 amp. It's got more power than I could ever want, but no tone controls. Is there a cheap (probably Chinese) tube preamp with tone controls that anyone can recommend? The only one I can find is this model, but it only has limited reviews. I currently use...

    Primare pre30 doesn't turn on

    A week ago I got this Primare PRE30 from a friend. I'm used to working on older gear so I didn't promise anything but said I would try. The unit doesn't turn on (not even the standby indicator). The power supply delivers all the right voltages and all the opamps seem fin (+/- rails are there and...

    What should I replace a Sony TA-E900 with?

    I have been using a Sony TA-E900 preamplifier for many years and have loved it because, to my mind, it has the perfect balance of musicality and detail. It is not too warm and mushy like some valve amps and not too harsh and 'in your face like some solid state ones. Unfortunately it now seems to...

    Preamp 3800, anybody using it with two power amps?

    Hi everyone, I have a 140 Power amp without a proper preamp and I'm considering both a 250 power amp and a 3800 pre. Maybe I'd go first for a pre and then for the second power amp. Anyway I've read in the manual that the 3800 is able to "feed" two power amps *simultaneously* Now the seller...

    If you had a choice between these 2 preamps...

    The Pro-Ject Phonobox DS or the Gram Amp 2 SE Which would you pick and why? I'm running a Debut Carbon with Orto 2m Blue -> Sansui 2000a -> Focal 807v's Thanks P.S. I spin mostly dub/reggae and classic punk and alternative with occasional bouts of jazz and metal.

    Mcintosh C-28 thoughts and recommendations.

    Hello all! Just picked this up yesterday for a great price-all original with manual and paperwork, great cosmetic condition and looked at by a tech at a trusted location for sales and service. It is in working condition, just a few scratchy pots. From what I've read, people either knock this...

    Help with ARC Preamp

    Hi all, I've enjoyed reading posts on AK for a while now, but this is my first post. I've recently acquired some new gear: an Adcom GFA-555 and an Audio Research SP-6c. When I got everything hooked up and switched on the SP-6, nothing happened. The green LEDs for "pre-amp on" and...

    G-7500 Phono

    I recently picked up a G-7500. The thing looks and sounds awesome and is definitely an upgrade from my early '90s pioneer receiver that I was using. The only issue I am having is with the phono preamp. The right channel is working and sounding great but the left channel is not playing anything...

    Chinese Marantz 7 preamp clones any good?

    Does anyone have experience or opinions on the Marantz 7 clones available cheaply on the net, kit or otherwise? Is there such a thing as a great, newly built, tube preamp, with or without phono stage on board?

    Adding a Pre Out to a Luxman R-1050

    Morning All, I currently own a Luxman R-1050 and truly enjoy the sound from it. However, I have also been presented with an opportunity to get my hands on a Jolida JD-302BRC, which although an integrated, has no phono input, and overall limited inputs. So my thoughts were to use my R-1050 as...

    YAMAHA C80 & C85 PREAMP HEAT SINKS

    I have noticed the heat sinks in the C80 & C85 preamps have a threaded hole for a machine screw. My C80 & C85 do not have the screws that secure the sinks to the PC board & they do move a little although the solder connection is fine. I purchased them used so is this normal or has someone...

    Marantz 170 DC Amp has no power on/off how do you properly manage connecting to power?

    Hello, I recently purchased a Marantz 170 DC Amp and have it paired with Marantz 2270 as the preamp. There is no power on/off button on the Amp. The manual says to plug it into the switched AC plug in the back of the Pre Amp (2270) - That works fine, except when I go to turn off the 2270 there...
