Once the bolts and washers/screws are in place the HS194-ND fits fine......no hacking.

Well.... were back in business.


It bothers me that I don't know what went wrong. I have tested and tested and compared measurments to the new transformer. And everything checked out the same.


I had a bad feeling that it might not be the transformer. But regardless I figurded I would wire it up and flip the switch. All the tubes lit and everything seemed fine. Weird.


I'm just glad to have it back. I listen to it daily so being with out it SUCKS!!



Thanks for everybodys help.

You'd be surprised on what can go wrong-when I finished my Simple SE i was scratching my head for ages trying to figure out why 1 channel was not playing any sound...turned out it was my ipod's left channel giving away

It makes great sounds now with jj el34 in tirode, transcendar opt, obbligato 70uf cap and ...and a sony mp3 walkman

Default output tranny ???

Anybody try the Magnequest 10 watt Robin Hood RH-60's? Would the 15 watt RH80 be required?

Yeah. I'm just glad its back. I still don't know what caused the problem. I'm just hoping it was a QC issue with the transformer. The new one hasn't missed a beat..


I think I'll be trying some EL34's pretty soon. I 've noticed a lot of people here like them with the SSE.....

I can check again if need be. But the last time I checked my B+ voltage was around 489 volts.


My question is. Can I run EL34's with a B+ voltage this high? Or do I need to take it down a little?


If I need to take it down a little. What size resistor do I need to be looking at. I believe there is a 560ohm resistor in there now. What ever George recommends on his site is whats in there.

I have an itch to try some El34's.....

I think it will be a little on the hot side for them. 680 or 750 would be a better choice. 560 is a little hot on my amp, which has about 460 B+. Not plate glowing or anything, but pushing them hard.

My SSE only has 8 ohm taps.

What would happen if I ran a 4 or 5 ohm speaker?

I can't remember which OPTs you have. If you put a 6-ohm load on the 8-ohm secondary, you can then apply that factor to the primary. So if you have a 5000 ohm primary, the tubes will see a 3750 ohm load.

Of course, it's not quite that simple. Since the transformer was designed for a certain primary impedance, doing this will saturate the core more than intended and so forth. If you are keeping well under the power rating of the OPT, then you should be able to get away with it. When you push it, you will start getting more distortion than you would have otherwise. Adding CFB can help compensate for this a bit.
