At first, their biggest 807 amp was huge and tall in the rack space; the very desirable A-255. That was my first logged memory.

Now, you post a pic of an Ampex but say the Altec amp was running 6146s...so...was it the 1430 or 1530 ? Regards...

Guy wants to sell the pair, still wrapped up in the packing he received it in. Looks damned heavy and large so I am hesitant to pick up until I know what I have. Plus it is kinda buried in the storage locker....more work involved

The number 1430 sounds familiar, I'll look it up. No dice,as of yet, however. The owner remembers the designation as being 14 something. The owner and I are getting along in age, so memory starts going, so my apologies in that regard.

Supposedly non ultralinear , fixed screen grid design ( which I like).

Way back in the 70's there was a company called Renaissance Audio.
Claimed 6DJ8 family was the best and highly touted the Peerless outputs before the ultralinear designs. I believe this amp uses one of those design trannies. Certainly there's a lot of iron and big ones on the chassis.

Even claimed that they used diamond cross section wire for winding to eliminate the air gaps. I've never seen verification so am apt to dismiss the idea. Other have claimed the w-6 used similar wire, FWIW. I do see MWS listing diamond shaped transformer wire in their catalog however.....

Solen claims to use hexagonal cross section wire for their "perfect lay"inductors. I can see a diamond cross section wire would be self tightening as you wind so there is some merit in the idea......
