F-300B RS / RSR
Our third generation 300B stereo power amplifier
A 300B “statement” amplifier for Real Serious 300B Fanatics (that’s a technical term!)
Over-sized stereo chassis (20" wide by 12" deep) allows space between components, as well as, use of oversized flagship 300B output transformers that is made to our specification, it is capable of a staggering 30 watt output.
The "beefed up "power transformer is also designed by ourselves to handle the extra voltage on this design, as well to have running temperature and quietness to the refinement level we wanted.
Top-of-the-line power and circuit components, including Mundorf Silver or Silver Gold oil coupling caps of your choice, Finale's own Pink-Lingu RCA and choice of CMC or Cardas binding posts , and Furutech rhodium IEC AC Inlet hardware
Dual individualized stages premium power supply electrolytic capacitors (e-cap here and after) for superior power supply to the tubes (one e-cap) and amplifier gain stages (2 e-caps) — featuring high-end Mundorf “M-Lytic” capacitors or same grade e-caps specially optimized for audio applications
Dual choke transformers setup for superior AC filtering on each section. One of the choke to feed the tubes and its dedicated power supply E-Cap, and the other choke to feed the dual e-caps to the power supply stages, along with the high quality made power transformer making it one of the quietest 300B tube amp from around the world.
Finale's specially designed 12AX7 driver stage, optimized for single-ended triode tubes - complete hand-wired point to point
Individual 300B Output Stage, each 300B tube is being feed, run and cooled on its circuitry board for best separation, efficiency and stability
Tube Rectifications with QQQ Japan high grade 8-Pin Tube Sockets
Finishes - 9 of our in house colours, or add $500 USD for your favour car colour or $2,000 USD to upgrade to copper chassis (shown above).
Expected weight: >50 lbs.

as well Stereo Parallel Single Ended 300B Dual-Mono Power Amplifier - F-3008 PDM
Pure Dual Mono design, each channel's own output, choke, power transformers and tube rectified power supply stage on to the same chassis - Total 6 Transformers.
DUO Feedback Technology, Double the bandwidth, higher the efficiency and stability, lower the distortion and noise, and beautiful curves of both measurements and image of the body.
Complete suit of Hashimoto (Sansui) Transformers
NEW FLAGSHIP OUTPUT TRANSFORMERS DESIGN BETWEEN TRIODE LAB X HASHIMOTO - Newly developed for Parallel 2A3/300B/45
Mundorf Supreme Silver in Oil Caps are voiced and used across the range
Class A 15 Watts+ (Conservatively under-rated)
300B Tubes 4 Pcs, 6SN7 Pair, 12AX7 Pair, Pair 5U4/274B Rectifier Tubes
Chassis same as F-3008 300B Integrated (Shown below blue unit), with many more condensed parts and transformers, 6SL7 will be used if doing the PDM as an integrated amplifier. 5U4 AND GZ32/5V4 Rectifier Tubes are recommended and all ideas to be matched.

Finalé F-300B Stereo Power Amp (MKII)
Debut 2013 - 2018
6-7 Watts Class A Auto bias (@ 1% THD)
Classic tube rectifications, DC Heated for quiet operations
6SN7 Drivers Tube x 2 , 300B Pair , Rectified by 5U4 / 5V4
Design concept: Complete individualized stages - the driver/pre-amp, outputs and rectify / power supply stages. And on the 300B output stage, each tube is fed, ran and cooled by its own circuit board for best separation and stability. This is easily some finest flea watts and what we call an appropriate 300B SET amp - if not the term "high-end" which often falsely used on the market. The design also applies DC-driven heater to minimize hum and noises, on the drive - it features a 3-stage triode amplifications for supreme musicality and drive. A solid thick gauge aluminum chassis is used to start off a stable and stiff foundation for the construction. To be the best, reliability and specifications are both included.
