※Limited-time sale until noon on December 28th 80,000 yen → 75,000 yen Thank you for viewing. This is the EL34 version of the TRK-3488, which was released as a 15th-anniversary model for Triode and became a popular standard product. Due to the self-bias method, you can use EL34 and KT88 vacuum tubes without adjustment. I purchased and assembled it as a kit model, and I think it has been in operation for about six months, with about 30 hours of use. After that, I kept it as a decorative object in a corner of my room, but I decided to sell it so that someone who will use it can take over. I tested the sound, and I thought it was working normally at a novice level. (Please forgive me as I don't know the tolerance level of a maniac) I am selling it at a price lower than the market price, so please consider purchasing it only if you understand this. The items for sale are the vacuum tube amplifier, the installed vacuum tubes, and the power cord only. The instruction manual can be downloaded from the official website. The TRK-3488 was designed as a 15th-anniversary model for Triode Corporation. It returned to Triode's basic philosophy of the joy of creation and debuted as the first in the TRK series. The concept is 'Enjoy EL34 and KT88 sound with Class A amplification', and with the self-bias method, you can enjoy the sound of two types of vacuum tubes with the simple flick of a switch, without any adjustment.
