    Power amp for my Sansui AU-555a

    Hello, I have a fully recaped Sansui AU-555a in almost pristine condition. I 've read here and there that it had a very good preamp stage, and that it sounds like a tube amp. Unfortunately I have no experience with tube amps, but they have been attracting me for a while and I wonder if it...

    which preamp to match an M-65, klipsch Heresy 2 and TT?

    I just found an M65 in perfect condition (supposed to be...) that I should get on friday. I mostly use my turntable, and also an nvidia shield TV with kodi to play music through my SMSL A8 DAC. The SMSL would be used at first as DAC and preamp. But I suppose I could find much better. I read...

    NAD 7240PE recap, rechip, reconfigure & repurpose - a.k.a. Duncan's Folly

    Here's a story about how a recap job on an old NAD receiver got out of hand. This 7240PE has been doing duty as a preamp only. A while ago I decided to pursue optimizing the preamp section by the usual means: improving power filtering and signal coupling, updating op-amps where applicable. But...

    1989 Technics SA-R477 New Class A

    Just picked up a nice clean Technics SA-R477 from a local Goodwill for a very fair price. I frequently buy from this particular GW and for the most part I’ve been lucky. This Technics is a solid receiver! Early Dolby Surround, not Dolby Pro Logic. It has A/B front speaker outputs and rear...

    FX-AUDIO- TUBE-01J

    Hello all! I am curious if anyone has experience with this buffer/preamp? Specifically the Japanese edition with the gain switch? From what I have read, the tubes should be swapped for the GE JAN 5654W. And since this is the Japanese edition, what kind of power supply should be used in the...

    DIY Preamp: Any Ideas For A Simple Kick-Ass 3 Input Design?

    'twas a sad day when I recently put almost my entire vintage collection up for sale. All that remains is a Hitachi turntable, Kenwood KR-9600 receiver, Luxman R-117 receiver, and Yamaha M70, C70, & T70 separates system. The Lux will stay behind as my power amp along with the Hitachi turntable...

    Marantz 2325 Left Channel Pre Has No Output

    Hi Guys, I recapped the pre-amp board (PE01) on my 2325 and am not getting any output on the left channel. I am running a sine wave from an audio generator into the AUX RCA inputs and am monitoring through the headphones and Tektronix 465. I am only getting output on the right channel in the...

    I have a preamp with a remote

    I have a pre with a remote. A lot of people here say the KC rack series preamps are junk and holding back the rest of the system. I couldn’t find someone with one and discussed why it was bad. I wondered if everyone was just repeating what someone else said. I was curious so I’ve been on the...

    Stromberg Carlson RP-766 C Restore

    sansui ca-2000 preamp vs au-1000a int amp preamp

    Just curious which would be the better preamp. I have the au-10000a int amp which I like. But would the ca-2000 preamp have better performance thru a "quality amp", than the au-1000a (separated) preamp going to the same "quality amp"?

    Hitachi KS-2400H Phono Preamp?

Anyway, I'm testing it out today and it appears that the phono input doesn't have a preamp built in. I've tried a turntable with a built in preamp switch to...

    Custom Tannoys/amps Identification

The drivers need to be refoamed so I’m having a local place do that. The cabinets look to be custom built and are HEAVY. Each...

    Mc225 to c27 stereo wiring help

    Hello AK! I’ve recently changed my speaker wiring setup to go from the mc225 amp to the c27 preamp so I could use the headphone output. I’m reaching out to the AK community to see if maybe someone has experience with biwiring to the speakers directly from the preamp — and perhaps would be kind...

    Replacing AV receiver with ?

    The more I reading I do in audio forums, the more I realize I probably made a mistake in purchasing a Yamaha TSR-7810 when picking up a pair of AR-90s to replace my JBL 4311s. I knew I would need an amp with proper power for the 4 ohm 90s, so I just found a receiver with pre outs to connect to a...

    Hafler DH-101 hum & crackle

    I have recently acquired a Hafler DH-101. It sat on a shelf at a local store for a while, so I'm sure it needs a good cleaning to start.

    MC2205 - Looking for a Preamp

Later I acquired a vintage Marantz 1060 so that I can hook up my turntable, PC (playing digital high-res material) and CD player into it and use it as a preamp to...
