【Junk Item】MIC2200 ULTRAGAIN PRO 【Discontinued Product】
Product Details
Power confirmed, but no sound output.
The cause may be vacuum tube degradation or disconnection.
There is a history of vacuum tube replacement, so the replacement work is likely to be relatively easy.
The vacuum tube used was an ELECTRO-HARMONIX 12AX7EH, which can still be purchased at Sound House for around ¥3,700.
