I used to have the TL 2.5. If you look inside quite a bit of room to make upgrades or improvements.
1. coupling caps
2. bypasses on main filter caps.
3. bypasses on the coupling caps.
4. soft recovery diodes in the power supply.
Do not know of any kits that are available, but the unit is not hard to work on.
