I had an RP-60 which also ran 7355 tubes. It was a fantastic sounding receiver. I modified it to run 7591xyz tubes which worked quite nicely. I'm sure that the new 7591s could be made to work as well.
5881's are a bit closer of a sub. The 7591xyz was basically a re-based 5881, which, handily, is what a 7355 is already. The 7591xyz happened to have a virtually identical pinout to the original 7355, making it a right fine sub with no mods needed.
I was close to re-wiring my DS-225 for 5881 tubes, but I came into a sleeve of NOS GE tubes for small coin. By the time I figured up the cost of a new quad of tubes plus my time to rewire the bases, the NOS tubes were the choice. The difference was like 20 bucks, and I figured my time was worth that much.

Type 7355 has about 30% more gm than a 5881/6L6...not so sure I'd call t a re-based 5881. That and they look nothing like 5881's; it looka to be in between 7591 and 6L6...nice tubes in any case...
cheers,

I'm a Bogen owner of several units, seems to be a very nice piece of gear.
May have been manufactured at the (Bogen) Lear Zigler Factory in Paramus, N.J.

Zandru, thanks for the links. Yes, the RP-230 was made at Lear Ziegler, stamped on the chassis. What units do you have?
Thanks again to everyone for the nice comments and discussion.

That is a fabulous collection. The 200A's are absolute monsters. A quad of those babies. Wow. How about a pic or thread if already here?

That's about all I could ask for, sound wise. Sounds like you picked a star for your only tube.
rpampt, that is gorgeous eye candy. Candy apple red. Muy bonita.

Posted b4, but here is my DCG modded Bogen MO200a converted to 6550's and 100+ wpc.
Sorry that is way too much amp for you ....
Wow I have heard some early Bogen and at 35 WPC, they were very sweet, I am just trying to imagine what it would sound like having all that reserve power into a set of Khorns or La Scalas...
So how do you manage your days with that permanent wall to wall grin?

I don't know much about tube amps but I know enough to buy one at an estate sale for 4$.
I know this is a bogen db-110 (g?) and it works. I have it hooked up directly to some old realistic Optimus 1 speakers and have tried all the inputs. I don't know exactly how to use this the most efficient way. It looks to be in very good condition. I wonder what it would be worth if I sold it. The only issue I notice is the small light bulb in front went out since I started using it. All of the tubes light up to some degree but not equally so I don't know what the condition of the tubes are. The 3 big tubes say GE Electronic tube on it.
Can anyone give me some info on this particular amp, how it should be used, and what value it might fetch? Thanks!

OK update....found the www.alliedcatalog.com website and found out where it fit in the picture. In fact spent several(!) hours perusing through pages and pages of really neat old stuff.

I have a Bogen RF-35 that my father bought new, probably around 1964. At the time, it was considered top-of-the-line. I rarely ever see this model come up. As an amp its great, as a receiver its amazing. The only downside is that it is sometimes difficult to tune in to some stations on the lower end of the dial. But when it does, it sounds so sweet.
