I have a Wakonda pcb. Haven't compared it to a Lingo 1 but like that it's contained (under) the deck. One less box.
Eventually, I'll $pring for a Radikal but until such time, I'm happy with the Wak.
In terms of your friend's buying options, I'd suggest the following:
1. Check with the dealer if the Wakonda has been serviced recently. It is likely to be at least 25yrs old and the caps may have gone/ or will soon. Mine did just
last month after 4.5 years of steady service. I've discussed having it reconditioned with Darran at Class A (Sheffield) and Johnny at Audio Origami (Glasgow). So, should it eventually happen, your friend can be taken care of.
2. It is
significantly larger than a Valhalla - as you'll see in the images - and Peter @Cymbiosis will confirm that it takes a well qualified fettler to install it properly below the top plate, on account of its' size. Another question for the dealer.
3. £250 for a Wak; or approx £400 - £500 for a Lingo 1. You pays yer money......
Some background...
They were produced in very limited quantities and mainly gifted to staff once Linn decided they wouldn't release to market. In Sept last year, whilst Peter Swain was installing Cirkus parts and Kore to mine, he was visited by ex-Linn employee, Bill Livingston who now operates Dynaudio UK. Bill remembered the long and passionate debate that took place at Linn HQ, with the Marketing team keen to launch the internal dual speed motor (they'd done this with the entry-level Axis deck, remember) and R&D dept insisting no. The latter eventually came up with Lingo, of course.
