●Product description: This is an old "vacuum tube art radio" that is in working condition and the manufacturer is unknown (the speaker and electrolytic capacitor are marked National, and the two IFTs are marked TRIO). .... The exterior case has been painted with a similar color oil stain and varnish to make the most of the wood grain.The case has some signs of wear due to the passage of time, such as the back cover being missing, but a new speaker cloth (flower pattern) is available. It has been reupholstered with art cloth) and has three original dials and knobs, making it a device with a good silhouette. (We made a new one to ensure a perfect fit). The vacuum tubes used are a total of 5 ST tubes: 6WC5 / 6D6 (6C6 was included when I got it, so I replaced it with the official one) / 6ZDH3A / 6Z-P1 / KX-12F, and the speakers are original permanent type. A speaker is attached.The dial operation consists of ``power switch with sound quality adjustment volume / variable capacitor drive / volume volume'' from the left of the front part. In addition, the main work this time is ``Replacing the speaker cord with safety in mind / The electrolytic capacitor in the power supply smoothing circuit was NG, so I replaced it with NEW ``22μF 450V x 2'' to restore the condition / NEW Replaced the two pilot lamp bulbs / The dial string was broken, so I replaced it in good condition / The receiving frequency band was unstable, so as a countermeasure, a "variable frequency transmitting coil" was installed on the cathode side of the high frequency amplifier tube. Since the ``trimmer'' was out of stock, I installed a new orthodox ``trimmer circuit'' and restored it to its original condition. / Finely adjusted the variable capacitor, transmitting coil, two IFT, and trimmer screws to obtain the best reception frequency. It is considered to be a fully operational product, with settings set / oil maintenance completed on each rotating part such as the variable capacitor, etc. The inside and outside of the chassis has been cleaned, and he has an old "vacuum tube art radio" of unknown manufacturer, which is in working condition and has been serviced with no scratchy sound on the volume and switch system. By the way, the size is width 38.5cm / height 24.5cm / total depth 18.5cm, and weight is about 5kg.
