Couple Original A-470s

[Hogy]

Why did you have to fabricate a botton plate? Allied still sells the OEM plate.

Not fabricate, fit. The OEM plate comes with only a few holes drilled, the rest of them Ken drilled by hand. The spacing isn't always even. You have to copy the existing pattern to make it fit.

got it. Dave's email was a bit unclear. He made it sound like you built him one from scratch.

[Blackburn]

Got em today... After a quick chase with the mailman, who missed me while I was out and was going to have me fetch them at the office... Until I caught him when he made another round on my street!

They're in fantastic shape. Just need to transplant one into the amp now.

[Colossal]

Very nice! Install and report please!

[Blackburn]

Indeed! I'm anticipating the end result so much, but the work is just soooo laborious. The second most troublesome replacement there is. It's not even that it's all that difficult, just so damn tedious with the unsoldering and no clipping. I always love it when the part can come right out with a snip, snip, snip... Not this one.

If I keep the Mercury OT, would an AC30/4 be a good build? I have a Mazda EF86 I've been wanting to use and having this ferocious OT sounds like it would fit nicely for a really mean pentode amp. Maybe I'll just send it back and look for more UL OTs if I dig these enough. Hmmmmmm....

Who's Dave? The owner of the Rocket I fitted a bottom plate for wasn't named Dave. Neither was the owner of "Tammy".

This thread is weird.

I'm Dave and I never owned a Wreck either. This IS weird.

Okay peoples, I did the horrid transplant today and can report on my findings. I ended up having to drill new holes in the chassis and remove some things and put them back after the fact. It's pretty nuts doing this with all the tubes still in the amp, but I was very eager to try this sucker out and all turned out well.

Conclusion: I notice even more bass response in the Dynaco than previously with the Merc as well as a difference in the character of it. I really like how the tone stays together now. It's not black to white, but it certainly is holding together more evenly than before. As for the really clean tone, it still chimes beautifully and possibly with even with more bloom in the notes. There was also something I have trouble describing that I heard with the Merc in there. Almost a thinness or plastic kind of sound clean. This one exhibits no such malady. I dimed it for a few and it is still really nasty, but I hear less junk in the drive now. More straight tube tone. I'll be playing around with it in the next few days and really getting an idea of how much I like it.

Dave was name of the guy selling Joni. Ill go back and dig up his last name..

[redshark]

Maybe Dave was the guy selling the amp or the guy that finally owns it but I talked to the guy that owned Joni for a few years and his name wasn't Dave. That rocket had all pacific transformers and something a little bit diferent also a feather on the faceplate.

Wow, both Pacific trannies on that Rocket? I wonder if it was the 5.2K or maybe it was one of those extra sweet 6.6K Rockets Allyn referred to a while back.

[redshark]

Who knows!! maybe when Ken was getting prototypes for the rocket he requested pacific to make it itoo. Let's not get carried away by all the myth. Pacific was working with Ken for a while and in the last years Heyboer too and although there weren't any wrecks with Heyboer OT's there is @ least a rocket with a PT.
The PT is only used to deliver voltages that the amp can use in diferent places and as long as that happens efficiently is fine. The biggest impact on tone comes from OT and it doesn't surprise me one rocket has all pacific, well, maybe the choke wasn't pacific but for sure it was hammond or stancor.

I use dynaclone A470-S in my Rockets or Edcor and used one Pacific 4k2 as well for rjguitars build. I would not use a MM myself others claim MM is the cat's meow but I find that other brands of transformers work perfectly.

I hear you, Mark. I've been looking around and I think I'll do Edcor on one. M6 and great price. They look good too. If I dig it as much as MM or more, problem solved. I may even look into Heyboer as well. So many options.
