I felt the same way waiting six weeks for my transformers to be made.

Thank you for the link!
Regi,

Based on Dave R's results, it's well worth the wait. A very nice sounding amp!

Best Regards,
TerryO

I agree - you will be glad when it's done.

I've run 6550 tubes for several weeks, and couldn't be happier with the performance. Out of curiosity, I thought I'd try some EL34's. I've only used them for a few days, and haven't made any real one-on-one comparisons. However, it seems that vocals are somewhat improved (if that's possible!) with the EL34's.

Dave

My sincere thanks to everyone for the great comments. I really appreciate it.

The transformers were custom manufactured for me by Heyboer. If you will notice the specs, special attention has been given to the output transformer with it's 58 Henry primary.

FYI: I'm still planning on shipping your kit tomorrow. I'll send a PM with details.

Thanks,

Scott

I would like to know, if it is possible, the size specs of the enclosure. While the kit is coming, I want to prepare the outer protective layer.

It is my first tube amp; but as far as I am concerned, I am pretty sure that I will not leave a HOT light bulb charged at those god-only-knows potential difference waiting for any clumsy person (read, me) to beat them. That's considering I am pretty careful person. Think about the persons hanging around my house and not being tech-concerned. The only thing that may prevent them to beat the valves could be hanging a warning post, a big one, as big as physically preventing them to beat the valves

Sooooo.... I am thinking in placing some kind of mesh around the amplifier, as a cover. Being not familiar with the tipical approach to this problem in the valve world, I think that one of the most cost effective solutions could be to use a bird's cage of the same size and screwing in to the chassis. That's why I would like to know chassis measures.

What other ideas are commonly used to avoid physical contact with the HV components?

That's another question going around my head: being valves a so dangerous area with those so high voltages, I see no one concerned about exposing transformers and valves in a so explicit way. Some may even call it a pornographic way
Coming from the low voltage SS world, I would be called crazy if I even dare to expose to the outside a MINIMAL spot of a transistor, resistor, capacitor.... everything goes covered and outside the (pre-assumed) unconscious user's physical access.

Making that long story short, I am thinking in using that, of an appropiate size:

And through the way, you get a free handle to comfortably carry your amplifier anywhere you want

It would be great if i was able to match one of those covers (or other mfg.) to the provided chassis with the kit:

Hammond Mfg. - Perforated Chassis Covers (1451 Series)

Can someone please measure the total height from chassis to the top of the tallest valve? My estimation is that, if chassis is 3" tall, the distance from chassis to the top of the tallest valve should be around 4". An estimation made only by looking at the assembly pictures.

May someone put a rule for a second and give me a hand?

Oh yeah! I found something that should fit as a d*ck in the *** (spanish's expression), perfect match. It is P/N 1451-30, a mesh that measures 17"x10"x5.2". Footprint of the supplied enclosure is 17"x10", and Hammond is the manufacturer too, so it should match perfect!

Bad news are the footnotes:

*NOTE: These chassis covers are NOT compatible with any of our wood sided chassis.
I think I can always remove the side panels, their only end are aesthetics....
