3. Basie + Aikido, stepped attenuation Volume Control with remote selector and volume: The Basie+ pre-amplifier is (with permission) based on John Broskie's Aikido tube circuit. Much has been written by the DIY community. Suggested reading on the circuit concept and development here. Circuit performance and amazing distortion measurements here. Possible tube combinations here (note not all listed can be used in the Basie+ but most common 8/9pin can). Our implementation uses a 6X4 tube rectifier and choke in the power supply. Standard tube compliment is a pair each of 6CG7 and 5687. Gain is about 10db ie 1v in for 10v out). It shows extremely low harmonic distortion and has excellent power supply noise rejection due to the unique noise cancelling topology. Output impedance is very low (<250 ohms) and it swings huge output voltage. This linstage loves to drive a load. Sample unit with typical tubes measured into 75k (output rms/pk-pk/distortion):1v/2.95v/0.064%; 2v/5.71v/0.074%; 10v/29v/0.29%; 30v/84v/1.575%; 40v/108v/4.5%!!! The Basie+ just keeps putting out.

Subjectively the sound is open, lively, turn-on-a-dime fast, transparent etc BUT...still captures the full tonal tapestry of music. Basie + Aikido has a heart of song - the more you listen, the more music you discover.

4 RCA inputs, 2 RCA outputs, includes tube cage, remote (no batteries). non-magnetic chassis

Note re 4/8/16ohm speaker taps: Why? It is needed. Really. Nominal impedance ratings are often misleading. An 8 ohm rated speaker may be 6 or 12 ohms and often sounds better on 4 or 16 ohm taps. Always try different taps to determine which gives best sound. When the right tap is selected, soundstage will be bigger and sounds more energetic. Also 16 ohm taps allow using vintage high efficiency speakers. Connecting them to 8 ohms is a compromise.

LD Level Two++: LD Signature 300B SET Power Amplifier Premium Assembled: Pair of mono-block chassis complete with premium TJ300B meshplate, 6SL7, 5Z3P. Complete with parallel 6SL7 CCS loaded to drive the 300B. Premium parts: Optimized Tantalum/Kiwame resistors, silver wire, teflon tin foil coupling caps, Blackgate cathode and Panasonic filter caps, NI cathode wire wound resistor, teflon tube sockets, pure copper gilded speaker binding posts, pure copper gilded RCA, WE connection Obbligato caps, amorphous grid choke, DIYHFS filament supplies - in other words - maxxed out with all the expensive bits you'd never find in high end off the shelf up to 4X the price.

LD Three++: LD Signature 300B SET Power Amplifier Premium 91: Gold recovered from the archives of the golden age of tube technology has swing! This refinement of the famous WE91 circuit uses a tiny amount of local positive feedback (can be left out if the word 'feedback' gives you the shakes) to give flat response to 20K (the original 91 circuit rolls off at 10khz and has a reputation for sounding dark). Pair of mono-block chassis. Includes TJ 300B meshplates, Russian 310a (yes better than original), 5Z3P

Parts: Optimized Tantalum/Kiwame resistors, silver wire, silver mica coupling caps, Panasonic + Blackgate filter caps, NI cathode wire wound, teflon tube sockets, pure copper gilded speaker binding posts, pure copper gilded RCA 6 pin driver tube socket and 310A grid caps, new 310A/Russian (matched pr), WE connection caps (Obliggato Caps 47uf, 12uf), teflon tinfoil coupling caps, 4 x oil cap for ps, silver hookup wire, teflon tube sockets (2 x UX4, 2 X octal), DIYHFS filament supplies and manual. Everything included. ready to play. Inside View with all the other tricks

So why do we need a 'Lux'?

objective: drive a DHT power tube

choice #1: pentode. offers necessary single stage gain but high output Z. tendency for highs/lows to be bandwidth limited. Clipping: not nice. Sound is delicate, immediate and pleasant 'bouquet of tone'. Fast! and retrieves the finest details as it sweeps the sonic landscape. Can swing the necessary voltage but but don't ask it to lift heavy objects. the DHT needs more muscle.

choice #2: triode. gain-challenged, needs more than one stage. (Hi gain versions sound like solid state). Low output impedance, wide bandwidth, great slam and dynamics. can be used with a grid choke for greater perceived power. Muscular, but lacks the refinement and delicacy of the best pentodes; leaves behind some of the fine details.

choice #3: re-active interstage. pentode on the input. paralleled sections of a triode with a choke loaded cathode. direct couple to the grid of the DHT.
the DHT gets what it likes: lots of swinging volts and iron fist control, even when driving the grid positve. This is Lux.

the pentode does what it does best: gives tons of voltage gain driving the undemanding load of the re-active tube interstage. The interstage is loaded only with the following grid and cathode choke so bandwidth approaches DC to light and is sonically neutral, no cap coupling to the DHT. The DHT thinks the choke of the interstage is it's very own grid choke. And we still have our pentode!

add to this: dual 5AR4 tube rectification (tubes=tone), dual mono HT AND PS film caps for extra speed, lifting of the veil, no ecap smog

more: WE connection on the 300B for more quiet, more dynamics

Result: tone and refinement of a pentode married with the slam and dynamics of a triode - something like a ballet performed by Superman and Karen Kain?

Lux:
stereo amplifier
dual mono choke loaded power supply AND film caps on the B+ rail to the power tube anode
