I had a similar situation, if you unplug the amp and plug it back in does it go green (when you have it on) for a few seconds? What I read was orange means there’s a problem with the amp. Getting the cap kit seems to have fixed the problem as I have not had the orange ligjt since I replaced the capacitors.

Alright. After closer inspection (ie, ear real close to each speaker), my tweeter works, and the top two and bottom two speakers are producing sound but are definitely not as loud compared to the right Penta. But my midranges on the left Penta are not working at all. I am 100% positive the wires are connected to the same connections they were when I got them (and based on the lady I bought them from, I don’t think there was anyone messing with these before me..). Speaker wire going to the spring clips should be bypassing the internal amps right? It’s got to be a wiring issue right??

 

Edit: Also, I’m pretty sure this was similar to before I re foamed the mid range speakers. But I only played them for a few seconds to confirm they actually worked. I remember one being a bit muffled even then but I took that quickly as an issue with the foam rot.

 

One more edit I promise.. I think the other outside mid range speakers on my right Penta are also not working.. I double checked the wiring against the schematic and the speakers appear to be wired correctly, although I did not try the other side of the wires inside the speaker assembly.

 

I lied. One more thing. As I was messing around listening to music for a half hour or so, maybe longer on and off, I just realized that the base is HOT. Is this a product of the mid range speakers not working or is there something else potentially going on? The right Penta is warm at the base but not nearly HOT like the left one.

Thanks Martin! Could that be the reason the mid range speakers aren’t producing much if any sound? If so I’m pulling the trigger! Replacing the caps was next on my list, just trying to make sure I’m on the right path and not sinking hundreds into these..

Thanks this was where I was going to get them, unless there was another place tbe community went for this sort of thing. Cheers!

I just bought a pair of Penta mk1 speakers (see my freestanding post). And im planning on fixing the speaker surround foam rot and recap the amps. After doing a bit more forum research, it seems like some folks get their amp and crossover cap kits from a “Martin”. Does anyone know how I can reach that person? Or is there a link or post somewhere I’m missing? Apologies if this isn’t allowed.
