I have a couple of questions for the experts here. Quick background...
Our church has been using a Bogen CHS100B
100W amp to power a series of auxiliary ceiling speakers throughout the building (70v system - each w/volume control) as well as a Gentner hearing assist system via the line-leve/tape output. The amp began shutting down recently. Holding the reset button allows it to power on, but it eventually shuts down again. The amp is probably somewhere around 10 to 15 years old and hasn't had any issues until now. (Good recommendation for Bogen!)
Of course like most churches we have budget issues so we'd like to keep expenses to a minimum. I'm not sure what might be wrong with the amp, but I'm reluctant to pay to have it bench tested only to find out it's at the end-of-life cycle (not unexpected). If it can be repaired I'm worried about that cost as well, plus that something else might go wrong with it down the road due to its age. Perhaps I worry too much.
In any case, a more-or-less equal replacement is Bogen's C100
which when all is said an done runs about $400.
So two questions...
First do you think it is worth taking in to find out what's wrong? (Cost approx. $50 to bench test.)
Second, since we're only using it for the two tasks mentioned, is a like-for-like replacement necessary or would you recommend an ideally less expensive alternative? Due to the number of speakers, etc. it has to be a 100W RMS/200W peak amp minimum.
