Yes, I am always keeping sufficient stock of e.caps, ics, transistors, diodes, fixed caps, zener diodes, all resistors from 1/4 watt to 20W including fusable, fuses, pots, switches, jacks, sockets etc. As I normally work from very early in the morning, sometimes as early as 2 AM, finding the component that you want in our stock is very important! I also store transformers, coils and may other things. In fact, my service room is a mini electronic shop! (LOL)

Another wonderful repair work,counting caps changed,about 48caps,that would have taken ur time.Time taken to satisfy client,is a well spent time.To do this you must have hundreds of caps in stock.l am learning from you.Thanks

Many thanks for your comments! The manufacturers, as I have noticed are mostly different. I feel even the design of a circuit and choice of components/ values and rating used has to be blamed for such failures! Though this is very low!

indeed Henrique, no doubt that Parasuraman is taking the cleaning and e-cap replacing to a whole new level of professionalism! About the todays bad e-caps problem... I wonder if data exists that lists all those manufacturers on what capacitor brands to avoid if that is possible at all?

Albert, I agree with your comments. As a matter of fact, the actual problem is the poor quality of the Chinese e-caps, that forces the technician to change them all. Pointing out that some of them, if still good now, will be bad in a few time. I have enough age to remember the tube devices I´ve maintained since my youth, and even the first transistorized radios (remember the Spika). Many of these devices, still functioning, have the original e-caps, and in good condition (without ESR problems). At that time, one saying that there is a need to change all the e-caps of a device could sound like a non-sense.
Concerning the extra work for solder patching and cleaning the device under maintenance, I understand that this is the normal behavior of a competent technician. OK, it is extra work, but necessary. A quality of a competent and honest professional.
