Hafler DH 500 update?

The one wild card with Elizabeth's advise is the potential for damaging your speakers. If a cap goes bad in the wrong way, its just not the amp at risk.

Your call.

I'd upgrade it or dump it. Its too old to plug in.

If your speakers are fused, that may help protect them. Also, you could add your own inline fuse. Possibly a 1 and a half amp, to two amp in series with the plus terminal of your speakers. A low powered new amp could clip out and fry your speakers on the spot too. There was a recent thread with a guy with expensive speakers, and amps that blew the midranges just from playing them a little to loud for awhile. It depends on how much you want to spend, but I would still put fuses inline with them, new or old amp. If there is any sound loss that anyone could hear, it far outweighs having no protection after something may go wrong. Well respected hi-end speaker companies use fuses to save them.

Thanks...someone mentioned the color green but mine is a flat black. Also this amp does have inline fuses on each side. The fuse caps say 10 amp, but i guess you could use a lower rated one for added protection.

Larryrx, the amp manual states it comes supplied with 2 amp fuse for speakers. I don't know if those are the correct covers, or fuses for something else. They like the 2 amp apparently also. Read last paragraph, page 4 in link. That way you could decide. A 10 amp will let most speakers get damaged.
