Product Details

Spare vacuum tubes and silver-plated Teflon wiring (Photo 13) have been added.

This is a chassis with a cover for the SUN AUDIO kit SV-300BE.
It is a shared chassis for SV-2A3 and SV-KT88, and after modifying it for each, it was disassembled and stored.
It was used for several tens of hours (3-4 months).
Large mounting holes for the two output transformers are pre-drilled.
The volume control has been moved to the top of the chassis, so there is also a hole on the top surface.
The power switch has been moved to the rear of the chassis.
Some areas have had the paint removed for chassis grounding.
Neon PL and nameplates are not included.
Please check the attached parts in the photos. Many of the parts included with the kit have been replaced with my own.
The two extra 8-pin vacuum tube sockets are for KT88 (the 5U4G socket has solder marks).

The attached vacuum tubes, capacitors, resistors, diodes, and silver-plated Teflon wiring are listed below.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
