JBL SG520 preamp restoration recap repair service rebuild kit capacitor set
The scarcity of good, honest techs who can do good and reasonably priced restoration/rebuild of audio equipment inspired me to create this restoration kit. In today's day and age, it is difficult to find a knowledgeable technician who can service your audio gear properly. I have seen many poor quality restorations of equipment that cost way too much for their owners. In 99% of the cases, only a few parts were replaced, instead of a full and proper restoration job.
A proper restoration must replace all electrolytic capacitors on all boards. Do not fall for partial kits that restore just one PCB power supply, power amp, etc. This is not a good or proper way to restore your audio equipment. It is the same as with car tires; one should never replace just one tire and keep the other worn-out tires on.
A proper rebuild requires a full recap of all PCBs. On the other hand, if one succeeds in finding a good tech, the wait time is usually 6-12 months for the unit to be serviced, and costs are sky-high. I have been servicing audio equipment for many years and have developed deep respect for all good equipment. Knowing how amazing and warm these units can sound, I decided to put together this kit. It includes very good upgrades and improvements that must be done to the unit. This restoration kit will make a huge difference in the sound quality. All the parts are of high-quality Japanese Nichicon / Rubycon / IC / United Chemi capacitors.
