In a Nutshell
Impressive 2 feet wide table top all-wave + FM stereo radio with auxiliary inputs in solid teak

Introduction:
In 1954 Philips Holland started to produce "Bi-Ampli" receivers, that were very successfully selling. The radios had two separate amplifiers for high and low frequencies, connected to two separate speakers. One example of such a 'real' Bi-Ampli is the 1956 model B6X63A. Later this expensive crossover scheme was replaced by a conventional diplexer network, feeding two pseudo-stereo left and right speakers with different filter networks (Plano), but the "Bi-Ampli" logo was still kept. Reassured by the continuing success, with the advent of real stereo, the logo was even kept on this 1963 model B5X34A, hoping the public to assume that "Bi" now just simply stands for stereo.
Anyway the radio is a beauty, with its slanted dial front, its prolonged shape (the radio is 2 feet wide) necessitated by its true stereo design and its cabinet from solid waxed teak wood. It is a hybrid tube/transistor receiver, using 9 tubes, 6 Ge transistors and 14 Ge diodes, to provide FM stereo (up to 108 MHz), as well as LW/MW/SW1 and SW2 AM bands, complemented by a phono input, that is used these days mostly for cellphone, mp3, and all that stuff. The transistors and diodes are all used in the FM unit. The radio sports two "Ferroceptor" ferrite antennas for MW and LW, and "RapidoSound", that allows to switch the radio off without disabling the tube's heater strings, so that it comes back without warm-up delay. The two speakers are 6" Alnico full range 5 Ohm AD3700M, the 800 Ohm version of which is highly appreciated by audiophiles as OTL (Output Transformer-Less) speakers (ref.5). As in OTL applications this radio uses the preferred (over EL84) EL86 for output.

About my Radio:
Disassembling the radio for service and cleaning is not an easy task, as has been realized by Philips, who published a special note about it (ref.4). A 6-page service manual for the B5X34A and 18-page manual for the B6X34A are available on request. The radio has been disassembled, cleaned, serviced, contact-sprayed, all defect mini-bulbs replaced, and reassembled. It is in mint condition, cosmetics and technics-wise, and plays perfectly on all bands. Watch a 18 MB! video by clicking on thumbnail 37. Please e-mail me (Kris) for any questions, ich spreche Deutsch, je parle Français.

For the techies only:
There are lots of technical details, all of which are already well documented. Search for 'philips "bi ampli"', 'philips rapido sound', and the two model numbers quoted above.
