EDIT: Put simply, if I could shrink this amp I'd keep it. Unfortunately it can't fit onto the shelf I bought for my new home office where the 2 channel rig now lives.

This amp had the top of the line "Super Magnum" upgrades performed by Rogue which includes the following:

- Hex Fred diodes in bias supply
- Screen grid resistors upgraded
- Polypropylene bypass capacitors in filters
- Bypass coupling caps
- PRP resitors in all critical spots
- Cardas binding posts
- Cardas RCA jacks (ST90 only)
- Upgraded wiring
- Upgraded small signal tubes
- KT90 output tubes

The amp runs a quad set of the big KT120's and the bass slam is there. I just rolled in some Sylvania Chrome Dome Black Plate 6SN7GTB's ($50) & RCA Black Plates D-Getter 12AX7's ($90) and it's buttery smooth. I am the second owner and have the original packaging and manual. It's just as important to me as it is to you that the amp arrives safely so I will make sure everything is absolutely bomb proof. It is an extremely heavy and big amp weighing in at 60 pounds. Please make sure it fits your rack or stand.

This amp will ship with the following tubes:

(2) RCA Black Plates D-Getter 12AX7 tubes
(2) Sylvania Chrome Dome Black Plate 6SN7GTB tubes
(2) Baldwin Raythoen 12AX7 Long Plate tubes (budget tubes that actually sound fantastic)
(2) JJ 12AX7 tubes
(2) Stock Chinese 6SN7 tubes
(4) Tung Sol KT120 tubes (these are about $50 each!)

I'd rate it 8/10 cosmetically. The little blue LED "power on" light recently went out. It looks like an easy fix with the cover removed because it is very accessible, but you'd have to confirm with Rogue about that.













I'm asking $1500 + shipping!

In the name of full disclosure, I fired up the amp tonight in a completely different system and heard a slight hum. I was able to hear it from my listening position about 7 feet away. This hum was not at my previous residence. So I swapped my main speakers in and the hum was significantly reduced. I didn't have time for a full diagnosis but I'm guessing it's a common ground loop at my new house.

EDIT: The hum was caused by my Rogue Perseus preamp. The preamp was sent into Rogue for upgrades. Now I cannot hear even the faintest hum from my listening position with my Totem Hawks or my Pioneer SP-BS22-LRs modified by Dennis Murphy.
