Did you check the fuse on the sub amp?

No, will look for it right now….

OK.  Let's think this thing through.

Your Supratek had the left channel die.

Your left sub is dead.

Why?

The last time I checked, both channels were now dead on the Supratek. Jack wants me to hook it up one more time before I send it off to North Carolina under warranty and I was going to do that tonight.

To the best of my recollection, all of this started with the addition of the subs. By that, I mean the very loud and concerning thump in the left channel coming out of the sub when turning the Supratek on and off. I think starting off, I had the Rythmik toggle in the on position, then I switched it to standby mode for operation.

Now I will admit that my usual mo was to leave the  Starkrimson amp on 24/7 and just turn the tubed Supratek preamp on/off every night for listening. Whether it was an interaction between these three pieces of equipment, I have no idea.

Dave

Chances the left channel going out on the Supratek was related to one of the 1950's RCA's I sent him but could be something else. The other tube is apparently still good.

2 new /different up and running puuuurfect.

Nick, Oh fun, NOT!
Brian must be really scratching his head.

 Try his hum test. With the sub on green. Take the cable out of the Pre. Hold on to the positive male pin on the end and don't hold the grounded jacket on the plug to the cable. It should hum through the sub. Turn crossover and volume all the way up .

AND don't mention my name.

Mums the word, Den 🤫 But there is no green light or red light either. There is no power that I can detect. Maybe it’s gone into “Brigadoon mode”….every 100 days 🤷‍♀️
If Brian gets it resolved, I’ll be a happy camper and then evaluate if they’re really worth having.

So glad your SVS are working perfectly!

Well, it’s official. After a few months of not being hooked up, I put my  Rythmik L12s back in this morning with my Hattor preamp and the left sub is dead. Changed power cords and outlets on the UberBUSS to confirm it. I’ll get in touch with Rythmik today….
Not to insult you, but are both sub switches in the auto on position?  I ask because I've done this before!  :rofl:

Oh, heck, I’ve done some dumb things before…. But this is a dead amp. Hooked up both subs again. No LFE, rather line outs from the Hattor preamp. Both toggles in off position and then auto and on. Played cuts from my “break in for subs” playlist and zilch out of left channel. No red or green LEDs, no sound, no cabinet vibration.

Brian from  Rythmik has already contacted me. I told him I could take the amp out and ship it to him to save him some shipping costs. Am waiting to hear back. I’m assuming these are cheapie amps and he’ll just send me a new one rather than repair it.

Well that's fun. There is a green power indicator light that's always on if it is receiving power.
Other than checking for its presence and verifying that a signal is reaching the unit, that's about all you can do.
I assume you also swapped left and right channels and still had no luck with the misbehaving sub.
If no signal is detected it will do nothing.
Scotty.

I haven’t run a signal through it, but the right channel sub has the red light indicator on when powered up and when the toggle switch is in the off position and that’s what I remember when they were both working and in the off position.
