Hi arnoldc,
miklos just answered the question for me
They are power chokes.
I tried step-up transformer in the other 6C45 amp but the result was not as expected.
I used this amp to power full range/OB center channel. I wired LL1582 as 1:2 step up, but the sound was terribly thin, lost most of the mid-low. And strangely enough, it didn't sound any louder. Maybe very bad matching in there.
I tried severl matching resistor but it still sounded that way. Eventually I gave up.

An externally hosted image should be here but it was not working when we last tested it.

I see you spent a lot of time polishing the electrolytics.
I never seen anything like it before. Very nice.
its amazing what a little brasso will do, the other one turned out just as nice.
caps are still good so i needed a way to clean them up.

Miklos - the output tubes are RCA 12aq5s. Except for the output transformers, and a change in caps to lower the input cutoff frequency, everything in my build jives w/ the schematic on the Decware forum. I think the output is around 12 WPC.
Note: last evening I hooked up my meager rega planar 2 & radioshack 9v phono preamplifier for a listen. While I don't think the radio shack phono pre really provides quite enough output voltage to drive el cheapo, I was none the less thoroughly impressed w/ the combination.

Here's my setup
All built during the last 18 months.
6J5 preamp - centre
2A3 monoblocks - Left & right
Remote PSU - bottom centre
Home built tapered quarter wave tubes with Fostex FE108E Sigma full range drivers.
Bass is supported by MJ Acoustics Active Sub (with phone on top) at extreme right.

It's a trophy presented by the World Designs forum members at their show last June.
Doesn't do anything but it looks nice amongst the other glassware
Steve.
Yep..big tubes have a lot of charisma...Doesn't do anything but it looks nice amongst the other glassware
No Bas it's a dead tube.
I won the trophy for progressing from valve audio newbie to having built a complete system in the space of one year using the advice of the forum members and my own reading of Morgan Jones.
Have a look here. This is my website which shows everything I built plus pictures from our forum meetings at the Eggborough Power Plant.

Now the name "EggFest" makes sense
