TRIO KA-3100 Integrated Amplifier

【Important】 The unit powers on, but intermittent noise was heard from the speakers even at the volume 0 position, indicating a malfunction in the amplifier. Therefore, this item is being sold as junk.

【Condition as of Saturday, April 18, 2026, 12:25:37 PM, Room Temperature 21.5℃】 (Please confirm with the radio clock in Image 2)
○ Power-on confirmed OK
○ No unusual odors or smoke upon powering on
○ Front panel switches operate smoothly. Rear panel terminals also appear to be in good condition, though slight rust is visible on the speaker terminals and ground terminal.
【Exterior Condition】
○ Minor scratches and dirt are visible on the front panel, but considering its age, I personally think it's in reasonably good condition (Images 1-4).
○ The rear panel also seems to be in pretty good condition, wouldn't you say? (Images 5-7)
△ The top panel shows noticeable marks from the feet of stacked equipment and rust (Image 11). It would likely look great if repainted.
△ The power cord had damaged areas and was wrapped with vinyl tape. Judging this to be unsightly (and potentially dangerous), I have cut it and replaced it with a new Panasonic plug. The cord length is now a little over 1 meter (Image 12).

Anything else... I will add more if I remember anything else.

※ While browsing online, I found a lucky individual who repaired a similar issue by replacing just one transistor. (I truly think they were lucky.)

For those who are looking for a toy to get lost in and forget about time! – though time becomes a constraint as one gets older – I await you for this once-in-a-lifetime opportunity.

※ Regarding packaging, I will strive to do my best to ensure everyone is satisfied.
(Please forgive me for the time it may take to package. m(_ _)m)
※ If I finalize my packaging plan, I may be able to ship it sooner.

※ Finally, to ensure a pleasant, one-time encounter, I must ask for your understanding that returns, refunds, or exchanges are not possible, as disputes over item swapping or tampering would spoil the experience.
