Parasound HCA-3500 power amplifier audio upgrade kit (tweak) for improved audio performance. Kit contains the parts needed to upgrade one amplifier:
- Holco feedback resistors recommended by John Curl. These are non-magnetic & non-inductive. Feature ceramic substrate and non-ferrous end caps. Heavy OFC leads provide good damping properties. Vintage made in UK.
- Soft recovery bridge rectifiers to suppress switching noise.
- Harris IRF-9620 FETs to replace Q5 (an IRF-9610 with known frequency shelving characteristics).
We are not liable or responsible for any amplifier damage or parts damage due to installed parts. It is highly recommended that one seeks professional audio shop services to install these parts. There are lethal voltages inside any power amplifier! We are not liable for user injury from self installed parts.
