Quicksilver mono amp
I read the above years ago in a technical report on the 8417. I was researching the suitability of various power tubes for triode connection.

The 8417 went out of production due to problems with the internal spacing of the grid-to-screen grid. Too many failures! Stick to the KT88/6550! 
One Amp To ‘Rule’ Them All....
Horses for courses! 
Altec A7 yay or nay?
I suggest buying a pair of JBL 2225 woofers (15 inch) for those Altec cabinets. I had a pair in large vintage JBL C - series cabinets. Can be found on EBay for less than $200/pair!  
3 things I learned from using MANY interconnect cables
@johnson0134: I am curious: what IC was the runner-up to the Chord Anthem? 
How long should a clearaudio maestro v2 last?
Keeping the stylus clean and applying Stylast before playing a side may extend lifespan. I do this!  
Camel ‎– Under Age – which to choose - Italian or German pressing?
Buy the Italian pressing (g/g) for €30 ($34.09) + shipping from "jadafne". Of the 10 listed on discogs this one is the    " best bang" for the bucks! Unless you want that €300 ($340.91) m/m copy from "robertin"? Don't be so stupid! 
Tubed Phono Preamp - Too many Choices!
I owned a Precision Fidelity C7 (designed by Bruce Moore of Paragon and MFA). Wish I hadn't sold it! Bought it new from American Audiophile NYC back in '78. Cost $600. Superb SQ! Competitive with today's units costing multi-kilobucks! If you can f... 
Best LPs to Test Turntables
And not to be overlooked: "1983, Moon Turn The Tides ..." from Hendrix's Electric Ladyland. Along with "Burning Of The Midnight Lamp". Jimi at his psychedelic best!

I will add Quicksilver Messenger Service's Happy Trails - "Who Do You Love" - and the two instrumental tracks on side 2. Recorded live. John Cippolina was a phenomenal guitar player! 
Best LPs to Test Turntables
I can recommend side 2 of Procul Harum's Shine On Brightly - "In Held Twas In I". A twenty-minute multi-section progrock suite!

@pgaulke60 : All the Weather Report LPs can be found used on EBay. I only buy original (non-digital) pressings. I assume that their later post-1980 music was recorded and mastered digitally. So look for their earlier recordings!  
A comparison between two DACs, one R-2R, the other ES 9038-based.
Spending money on a new device is a powerful incentive to believe that the new device is somehow "better". 
A comparison between two DACs, one R-2R, the other ES 9038-based.
All well-designed CD players and DAC's measure essentially the same. The oddball ones that use tube output stages are of course subject to the higher levels of noise and distortion typical of tube circuitry.

If DAC's really did sound different there would have to be some X factor that is responsible. Since the arrival of CD's and players in 1983, no such X factor has been identified.
