Congratulations Marvin. Norma gears are some of really nice ones to have and listen to. Looking forward to your thoughts on this one. It looks nice. Enjoy!
Having a great system definitely helps pass the time quite well!

Got this today from CL. 10amp Powerstat. Minty! The guy even delivered it to the house!
So my delight was quickly diminished the other day after I took that pic, left if there (yes right in the middle of the doorway, idiot) and the Mrs came into the office a little later then stubbed her toe! Boy did I hear it!

You heard it? I told you it would sound like Van Halen 's first album!!!!!
While I'm under corona house arrest I thought this would be a good time to do some comparisons. Having heard a rumor that fully balanced amps don't project the soundstage as far as non-balanced amps my curiosity got the best of me. So far I'm surprised that the little non balanced Proton d1200 is making a good accounting of itself. More listening is needed.

I do not think that was intended for the older SDA's, it was for the L800's only as far as the SDA side.
That's it! I coming over to quarantine at your house! Can I take your Harley out for a spin too?
You sure can if you don't mind riding a Kawasaki as I don't own a Harley.
The little 1200 is still surprising me with how well it pairs with the 1.2s especially since it's not my favorite amp on my other 2 pair of floorstanders (khorns+ads1530's).

I see an unusual shelf the amp is sitting on that I really like. It looks like some type of adjustable piston on each side. Is it part of the overall shelf? Can you talk about it?
I was looking at a listing of a D1200 on Reverb that was posted on Wednesday. Almost mint it said. It has sold immediately.

It's not a piston it's just an extra part of a stand I put in there as an isolation experiment. They made no change that I can hear so I'll probably remove them at some point.
I bet that 1200 did sell quick if it was priced right. I was thinking this d1200 is one of my better cost vs. performance items. In my case the Proton didn't cost as much as a pair of aftermarket handles on one of the Macs.
That 1200 is in very nice shape and that seemed like a fair price. My lighting is all original and getting pretty dim compared to that one and I'm thinking that should be my next project.
Thanks for the kind words and yes I use a 1000va dreadnaught.
A couple days ago I put a NOS SED 5U4G rectifier in my Decware preamp. I recently got it off Ebay and paid about $20.00 for it. Quite frankly I wasn't expecting much but after a couple days of listening I found it not to be a bad tube at all. Compared to the 1950's Tung-Sol 53YG it replaced, I found it clearer and with a larger soundstage, but also a little edgier and with a slight increase in glare. It also had a little more drive. The edge and glare were definitely there but it wasn't that bad. Just noticeable upon comparison. I could regularly listen to it with no reservations whatsoever. Maybe if I put some more hours on it some of the edge and glare will dissipate, but for now, it's definitely something I could live with. For $20.00, on my rig, I consider it a win.

I have recently found out (again) just how valuable a rectifier tube can be in a system. Congrat's on your new found sound!

Thanks Tom. I just got the Decware preamp and have been rolling quite a few tubes through it, trying to dial it in. As we speak the leading combination is a 1958 RCA 5R4GY rectifier, a BEL 6922 (made in India with Phillips tooling) input and a pair Voshod 6N1P-BN outputs. I tried rolling some other 6922's into the output section but due to the 6N1P's high heater voltage, I got a nasty 60 cycle hum. So, for the time being, I'm kind of stuck with the Voshods. Other rectifiers I tried include: a 1958 RCA 5U4G, a 1963 Tung-Sol 53YGT, and a 1967 Mullard GZ32. I keep coming back to the RCA 5R4GY though. So far the best compromise of the bunch.

I am currently running a NOS 5AR4 - Mullard from the 60's as my rectifier. Sounds like you have some tube stash to work with. Nice. Since I have a new pre with completely different tubes now, my stash will have to start from scratch.

I've been thinking about trying a Mullard 5AR4. Some other Decware preamp owners use them with good results. I have to remember to look for one when I go on one of my tube buying binges.

Set that around 85 volts and let it power your guitar amp, and you'll get a nice, old school Van Halen tone.
