I receive comments all the time about how modern amps are disposable and not repairable. Usually is starts with "my techs said it was disposable because of the technology", but in reality what they really mean is that they (the tech) is under-qualified to repair something they lack the education, tools, experience and skill set to repair. Sometimes, the tech is a DIY hobbiest, but that's usually not stated up front IME. Then it goes down the road with complaining that the company won't support or repair the amp, nor will it walk their under-qualified tech step by step through the repair that they shouldn't be doing in the first place. No company wants to spend the resources trying to walk an under-qualified tech through a repair (takes far longer than just doing the repair themselves), not to mention the danger and liability because they don't understand the safety aspects of what they are working on. Their interactions generally from this point into playing the blame game.
Here is a good example of a high technology amp (NeoPak 3.5) that came in for a SMPS (switchmode power supply) failure. This is exactly the sort of thing that I mentioned above, complicated technology, and an early implementation (over 20 years old!). The customer sent it here after local service techs told him it was unrepairable and disposable in spite of it being a bit of a collector's piece, as it was the second commercially successful (and reliable) SMPS based bass amp. Yes, there were a few others, but not many and for the most part not commercially successful/reliable other than the Walter Woods amps. Both the NeoPak and WW used SMPS and class AB power amps.
That said, the amp (which was in collector's cosmetic condition, easily worth ~$500) was repaired without any issues, the total cost was $165. Also, not a single electrolytic cap was even close to needing replacement (there goes that urban myth)!
THIS is the difference between a QUALIFIED versus an UNDER-QUALIFIED tech. My labor rate is probably twice that of the under-qualified tech, yet the qualification factor means that I spend much less time on the repair, the amp gets repaired properly, and the cost to the customer is less. Remember this when you look to get something (anything) repaired, amps, speakers and especially instruments. A qualified luthier for example, even if expensive, is worth paying more for because their greater skill set really does have more value... especially when working on expensive instruments. A bargain isn't much of a value when they return it in worse condition than they received it in.
