Hi Buddies, the WA22 is at home now.
biggrin.gif
When I opened the box and the amp came out in my sight, wooh, it's built so beatiful, heavy and like a tank. The stock tubes came with the amp are GE 6SN7GTB, Phiips Jan ECG 6080WC (metal base) and the Russia 5Z4G (I will never put this ugly tube into the WA22).

I then opened the cover underneath took a look with curious. Surprisingly, the 2 chokes inside look very cheap, I realized that in my ex-WA6SE, there are 2 better look chokes in use, these 2 are really crappy in look (yeah, just comment from the outlook only) the foil covered by some very cheap plastic tape, 2 wires from the chokes are soldered in each side of thf the choke and pcb. It doesn't look like what I've read in Seamaster and other members thread and pics, the cables are direct lend out inside from the choke. The 3 Nichicon power filtering caps were now replaced by CDE, it should be a Taiwanese manufacture, it look also cheaper than the Nichicon.

This is the innard pic from Seamaster's thread. (Sorry Seamaster, please lend me the pic to show the differ)

The pcb is different too, I think Jack is soldered all important component point to point but the trace on the pcb just make me feel it's no longer a fully point to point soldering gear anymore, it also happened on the DACT.

Anyway, plugged all tubes in and have it warm-up for an hour before initial listening. The tubes are stock GE 6SN7GTB, Phiips Jan 6080WC and Mullard GZ30, yes, I said that I will never put that ugly Russian rectifier into my amp.

The EML 5U4G is told that by Jack temporary out of stock, it will be shipped by the mid May.

Before listen to the amp and after look at what the component were inside, I'm quite upset

what will it sounds? But wow, just WOW. Jack has never make me down, this beast sounds very nice, solid and un-expected that what component it used. Very lush and beutiful highs and the bass is full with texture, not very powerful and impactful, it should be because of the tubes now in use. I will swap by Raytheon 6F8G and GEC 6080 for a try, see how much can be improved in sound.

I'm still a very happy Woo amp owner. And............. I'M BACK!

PS. Sorry for the crappy pics taken by my crappy DC.

Danny, your amp looks great. Your circuit board is double sided rather than single sided like on the first generation units. Probably done that way to make the signal paths shorter. Also, I like that your chokes have soldered connections, rather than being hardwired. I agree that the newer Woo's have less point to point wiring, but yours is no less than the first WA22's.

Thanks Glenn. But why a soldered connection choke is better than a hardwired one?

Other than that, the power filtering CDE caps not looking good than the Nichicon either, but anyway, it sounds very good, indeed.



Danny, it's just my personal preference. It's not better or worse.

OK my friend, that's fine anyway, it was there. But wondering I could swap some better cable for the connection.

Just put the GEC 6080 and Raytheon 6F8G with adapters, and it made by a very nice gentleman called Glenn.

Will up-date what they sound after some warm up. Some pics for the beautiful tubes below.

Hey dannie01: my WA22 chokes are also covered in plastic rather than foil as well but they are hardwired and not soldered.

I don't remember making any adaptors. I guess it's the age thing
