That's good, I only own my bike so I generally only have to worry about it, being able to fix it myself also helps save a little dough. I'm not sure, it's nice to have spare parts, transformer, heatsinks, potentiometers and all the components I could ever need to keep the other going. I'll have to think about it.
My Wharfedales? Best speakers I've had so far, re-capped mine last year and they sound amazingly good for being vinyl covered 80's speakers with arguably chinsey looking plastic (except for the tweeter that has a metal ring.) silver surrounds around the drivers.

I used alcap electrolytics in mine, makes me wonder if I should replace mine with film caps. I think my Wharfedales are a little to large for my room having 10" woofers and all, but man do they sound good. I had a pair of Trio S-120's and on paper they should have blown me away with what I was expecting, horn tweeters, 4" high/mid, 7" mid, 12" woofer all alnico, but I found they sounded really harsh and like they had too much mid range with no bass, even after re-capping. Quite the bummer.

Could be, the crossover was suprisingly complex in the Trio's They even had and attenuation switch which ragned from screechy squawk to muffled squawk...

Feels nice to have it all back together 100% now. I pulled the face plate off to clean it and re-soldered the front panel PCB to mitigate any future problems, replaced all the zip ties in the factory positions and now she's all back together and lookin' perty.
Oh and these things are worth their weight in gold, way better than a soggy old sponge for cleaning your soldering iron tip.

And it sounds even better than it looks. I have a question, is it normal that it makes a Thump kinda noise thru the speakers when first connected to AC? Kinda like when you first power up a cap coupled amp. The other one did this too.

I love how quirky Nad's are, thanks for the advice. I think I might experiment with putting some resistors or maybe trimmers in series with the lamps to see if I can reduce the brightness a bit to try and make the bloom a little less noticeable.

That's the idea, think I'll go with a pair of trimmers, that way I can dial them both in perfectly.

Will do.
Hello. I recommend buying these LED replacements on E bay
Are customized for NAD 705 including resistances.
Would anyone have a link to an ebay listing - I've searched but can't find them.
Thanks,

I believe the Yamaha CR **20 series receivers had solder issues on the bigger components. I can attest to the sound for sure! For those brief 5 minutes a NAD is working it's amazing!In all seriousness this NAD has really grown on me, I wonder what it is that makes some amplifiers sound better than others, that thing that makes drums, cymbals and other things the upper mid - treble ranges sound so defined and clear, and the spacious seperation. I can tell why NADs have such a following. It's by far the best amplification device I've owned yet.
Their amps really grew on me as well. I had a 3240 that I got in college and still have. It still sounds special today, even though I've added other NAD amps to the mix.
Thanks for this thread - following in case I ever get far enough in my technical abilities to do something similar!
