Thorens TD 124 DD
The original TD 124 was introduced in 1957 and has been used for decades in countless broadcast studios around the world. Ambitious music lovers also quickly discovered the highly precise turntable for themselves; a dedicated fan base has remained loyal to the TD 124 to this day.
Thorens is now building on this tradition with the completely newly developed TD 124 DD and continues it with innovative technologies. The purist design and basic construction are based on the original, but the height-adjustable aluminium chassis now rests on vibration-damping rubber elements. Instead of the original drive with friction wheel and belt, the new TD 124 DD uses a "High Precision" Direct Drive. This provides powerful torque, allows precise speed control, and keeps unwanted vibrations from the drive away from the platter.
Also new is the tonearm TP 124. It can be precisely adjusted in all parameters to the cartridge of choice and features an innovative anti-skating solution with a ruby bearing and a patented electric tonearm lift to facilitate gentle placement and removal of the stylus.
In addition to the extensive adjustment options, the enclosed headshell provides a great deal of flexibility when it comes to selecting a cartridge. The TD 124 DD also comes with an additional, slightly heavier counterweight that matches the Thorens SPU TD 124 pickup, which is available separately. This is an updated version of another legendary piece of vinyl equipment, the famous Ortofon SPU. Thorens has created the SPU 124 together with Ortofon for the discerning vinyl enthusiast looking for the extraordinary.
Thorens has payed attention to every detail when developing the new TD 124 DD to ensure that it meets the highest aspirations in sound performance. A high-quality external power supply unit ensures interference-free power delivery. In addition to the unbalanced outputs, balanced XLR connectors are also provided, which guarantee optimal signal transmission and thus the best possible sound when connecting the TD 124 DD to a high-end system with an appropriately equipped phono preamplifier.
Features:
High Precision Direct Drive Motor
Electrical Lift
TP124 Tonearm
Removable Headshell (SME connector)
Prepared for SPU Cartridge
Balanced (XLR) and unbalanced (RCA) outputs

Current, please, no voltage
It is worrying that, against all odds, audio amplifiers of all kinds, try to drive the loudspeaker with the voltage instead of current, claims Finnish electronics engineer Esa Meriläinen in his book Current Driving of Loudspeakers.
Info
Gudebrod 3T12V Preamplifier
$5500
3T12V is a single ended stereo line level input tube preamplifier.
The heart of this tube preamplifier we utilized a 274b rectifier also making it possible for you to roll tubes like a 5u4 or 5r4 rectifier.
The signal tubes are also capable of being rolled for that one of kind sound. We're currently using Psvane 274b-t mark 2, 12au7 genalex gold lion and a pair of Phillips Jan 12at7wc’s.
Paired with beautifully crafted Lundhal chokes and output transformers it allows our tube preamplifier to sing!
The Wenge wood sides are standard.
Comes with 6’ 14ga. Power cord.
Warranty is 2 years parts and labor, tubes 90 days.
All preamplifiers are made to order and take 3 weeks from date of purchase and are run for 100 hrs. before being shipped.
If local to the Illinois area we also offer in home demo's and installation at no additional charge.
Specifications:
Directly coupled on hand-crafted turret boards
Non-inverting
High input impedance, low output impedance
Auto channel balancing compensates for aging tubes
Ground lift switch
Frequency response: 20hz - 50khz
Gain: 5x (15db)
Harmonic distortion: <.05% in normal operation
Power Consumption: 17ma
Main Votlage: 120vac
Inputs: 3 single-ended
Outputs: 1 single-ended and 1 balanced (true 600 ohm load)
Dimensions: 19" x 15.25" x 4.75"
Weight: 25 lbs
