I also have black. Yes, I did not receive a cage with mine. Rest assured your package will be very carefully packaged. I was extremely impressed by the level of care attended to packaging.

Welcome to the club! Don't want to brag but do read my 339 review, or seems to have persuaded a lot of people. It is the 64jp tube though

 

[kaleb500]

I already did. 

 
A well written review I must add.
 
It was actually your review that alerted me to this amp in the first place. Otherwise I would have gone for something else. 

 

[kaleb500]

These two variants of the amp, is it both types of tube that are different, or just one of them?

 

[Liu Junyuan]

Just one, the smaller driver. input tube that stands on the outside of each side. Power/output tube choices remain constant.

 

[kaleb500]

Oh I see. That is interesting. I can use the recommendations for that tube then at least.

 

[Liu Junyuan]

Oh I see. That is interesting.

Try to find some Bendix 6080 power tubes.

 

[kaleb500]

Yea those seem to get high praise.
 
I actually already ordered a couple of RCA 6AS7G. Now that I know they are compatible I'll try these first. But I'll be on the lookout for more tubes down road. Bendix 6080 being on my list.
 
Are these what you are using now? Is 'Bendix' just the manufacturer?
 
Thanks 

 

[Liu Junyuan]

Good start. Those are great tubes, and they are the first I bought along with the 339, ordered prior to reception of the amp like you. I roll between tubes, but currently the Bendix are in my amp. Have no idea where the names of my tubes come from...

 

[kaleb500]

So this list of tubes that is designated for my spec of amp:
 
6C5, 6J5, 6J5G, 6J5GT, L63
 
Are these all driver tubes? My greatest fear it plugging a power tube into the driver socket! Are the driver tubes always smaller?
 
Thanks

Yes, they are the smaller tubes toward the outside. The power tubes will not fit into those sockets, so no need to worry.

 

[kaleb500]

Cool thanks a lot.

  Check out the Bendix 6080WB

II.b) The Bendix 6080WB Graphite Plates
Unlike all other 6AS7 tube types, these had solid graphite COLUMNS and not plates and are very heavy duty. They have ruggedized construction features such as extra supports and copper posts not found on other 6080 tubes. Regardless of branding, these were all manufactured by Bendix. These are a really good buy and an excellent alternative to the 5998. These tubes are sonically similar to the 5998 and are superior to with a noticeably airier sound without being prone to sibilance. 

Keywords: Detailed, Neutral, Fast, Punchy, Dynamic, Wide, Overrated

 
You forgot a keyword 

 Just my opinion though.  

 

[adeadcrab]

which power tube is better?
