    Calling All "Vintage" Integrated/Receiver Owners

    You will need to find a suitably experienced/qualified tech or hobbyist in your local area. Are there any general or vintage audio forums in Norway where you can search for someone? You could always try audiokarma.org.

    Absolutely! The restoration process would include an adjustment, heatsoak testing and monitoring period at the end of the resto. You’d only adjust the amp first if there was no intention of restoring the amp in the immediate future.

    Correcto - she's 100% original internally. An initial service would be the first port of call for an amp of this age - checking/adjusting bias and DC offset and cleaning/lubricating switches and controls etc. If the budget allows, a proper restoration will yield the best sonic results and...

    So, the Sansui AU Alpha 907MR was suffering from cracked side panels, as is often the case with late model Alphas that have copped a few bumps. The side panels are a type of MDF which are very smooth and have been finished with some kind of vacuum-formed plastic covering (as opposed to vinyl)...

    Lovely - the AU-317 is an under-rated gem, and that slimline form factor can be a big plus. I run a restored 317 as part of my PC rig.

    I'm luckily at the point where I've played around with numerous speakers and DACs at various price points, and have settled upon options which are not necessarily the most expensive components that I’ve ever owned, but are the best sounding to my ears. Same goes for interconnects and whatnot. I...

    A challenger to the crown has arrived... enter the Sansui AU-Apha 907MR! Lots of bitumised rubber sound deadening and Teflon tape to be found everywhere, along with the usual array of Elna Silmic Alpha Gold capacitors, RIKEN resistors and the big 13kg Tamura transformer. 33kg of Sansui goodness...

    Indeed, they are 33kg of Sansui's finest. The binding posts on the MRX are from WBT and are top-quality. The feet themselves weigh over 1kg in total. I'll post some internal pics once I receive the MR, although it looks identical inside to the XR that I have.

    Ah, glad to hear that Dad set the 907MR up for you to hear! The MR is the model after the 907XR that I currently run at my place. It's a very very slight evolution over the XR - slightly more detail, a tad less warmth. I'll be collecting the MR this week for some listening over the Easter...

    Yep, Dad has done a great job with those binding post conversion kits. Very clean and fully reversible if required - the way that all good mods should be!

    No, that's a file photo. A 907MR is all boxed up at Dad's place and awaiting it's debut at Casa Del Mac very soon. :)

    You'll need to perform some disassembly of the amp to clean the switches. I recommend DeOxIt D5 spray. Use sparingly, as it will flush out any damping grease and the like if you spray like a madman. The 707DR should be similar to this 907MR when you remove the front face:

    First port of call - a proper internal cleaning of the loudness switch (and other switches at the same time). If this doesn't help, there is a fault in the preamp or power supply circuitry which supplies the preamp stage. The loudness contour is essentially an EQ circuit which is switched into...

    Great speakers those - I once had a pair of gen 1 Axis LS-28 with a different Audax woofer and they were fantastic!

    The Eight Deluxe is a nice bit of kit. The original Eight is often described as the 'engineer's receiver' due to the build quality and design. The Eight Deluxe displays some cost-cutting measures, but is still a fine receiver and some prefer the sound of the Deluxe. There's really not a lot of...

    Given that I'm on a roll... I might as well share a few more pics of the lovely amps that have graced Casa Del Mac. A near-mint AU-20000: My AU-719 about to be fitted with a rare NOS faceplate! AU-888 AU-999: AU-7700: The huuuuuge Marantz 2500 - bulk power and an...

    I think you describe the difference well - some of the older Sansuis do indeed offer a 'lusher' sound which is quite intoxicating! Not everyone likes the later Alpha sound if they have become accustomed to the earlier Sansui sound. I do believe that system synergy and personal preference are the...

    Ah... I thought it was the 8006! I've had the pleasure of restoring two of these. They are lovely sounding amps with superb build quality. I was particularly happy with how all of the knobs and switchgear cleaned up with some careful cleaning and hard work! The deeply etched lettering on the...

    They are the AU-X701, AU-X711 and AU-alpha 607 MRX. All three are '607' series amps and are the 120/240V international models, as opposed to the 100V JDM models like the 907s. They are a very good entry to the alpha sound, as they are still 90/100WPC and have excellent sound quality, without...

    They definitely offer a point of difference vs the older Sansuis. They are more like the 7700 than the 717 IMHO, but are certainly cleaner and more resolving and the earlier Sansuis to my ears. We have a few of the smaller alphas (607s or international equivalents like the AU-X701 and AU-X711)...

    Good stuff - it is well worth your time to compile a short list of the essential things to be tackled, as this info has been built-up over many many years from techs and hobbyists who repair and restore these amps regularly. There is an evidence-based approach to why they recommend what they do...

    The 20000s are beasts for sure - plenty of grunt and a lovely sound. Likewise, the BA/CA-2000 combo is great. I also rate the sonics of the BA/CA-F1 combo very highly. A properly overhauled and modded AU-999 is superb, and the AU-888 is essentially a revised AU-999. The AU-517, 717, 519, 719...
