Internal maintenance has been carried out, and all details such as capacitors and terminals have been overhauled! The appeal of 38 is that it has a thick, thick tone that cannot be heard with current audio, and is surprisingly powerful. The thick mids and soft, rounded highs go great with the TANNOY speaker. As for the exterior, there are threads and rust spots on the back. Serial 10119132 (Asaina Tomonori)
Maintenance information: 2023.10.13 Maintenance completed (main part film capacitor replaced with ASC, rectifier diode replaced with first recovery diode), 2 deteriorated vacuum tubes 6267 on the main part were replaced, resistors on the main part were replaced, and since there was a crackling sound when power was cut off from the pre part, the deteriorated block capacitor was replaced. Operation confirmed) 2022.9.8 Maintained (1 output transformer (OY15-5) replaced. The coupling capacitor was changed to an oil capacitor. Empty tube sockets, electrolytic capacitors, block capacitors, diodes, semi-fixed resistors, micro SW, SP terminal replacement. SW/VOL is completely disassembled, contacts are repolished, and oxidization/sulfurization prevention grease is applied. Offset bias adjustment, input/output waveform confirmation, distortion adjustment, 1kHz sine wave, measured value 25W+25W sound output test. (Exterior repair/polishing/painting)
