What is the difference between the Beekman Bugle Boy and the Orange Globe?
There are also Tektronix matched pairs available.
Would appreciate advice on the exact type to pick for best sound (picture?)
Perhaps RCA labeled types are the sleepers?
- Orange Globe PQ - It appears that these are standard 6DJ8 / ECC88 with a fancy label, so you don't want to pay extra for them. On the other hand, if they have the 2-stage halo getter as shown in the picture that Jaywillin has posted, and you can get them at a good price, then these are the Orange Globes to get. Tektronix, HP and other labels on standard Orange Globes are fine, but again, not worth paying extra. True SQ and PQ tubes will be labeled 6922 / E88CC or 7308 / E188CC and have gold pins.
- Country of origin - Amperex 6DJ8 manufactured in England are, in fact, Mullards, and they will not sound the same as those manufactured in Holland....
- US-made Amperex 6922 and 7308 versus Holland-made Amperex 6922 and 7308 sound somewhat different. See Joe's Tube Lore for more info. I followed his advice in purchasing my US-made Amperex 6922 and they are to die for. :)
- Beekman Bugle Boy - I believe you mean Beckman. I purchased a pair of Beckman-labeled, US-made Amperex 6922 / E88CC, with gold pins. Mine are identical to tubes with the Amperex label, but I got them for considerably less. If resale value is important, it might be worth buying Amperex-labeled tubes. If sound is paramount, there are good deals to be had by searching for relabeled tubes.
- RCA did not manufacture 6DJ8 tubes. Therefore, every RCA you see was manufactured by another company, and very often, that company was Siemens.
In summary, I recommend that you try to find an Orange Globe with the two-stage halo getter such as Jaywillin and AFB have purchased. (that is, not an A-frame) . While I do not have these OGs, I do have the white label Bugle Boys and the A-frame OGs and both are excellent tubes, as well. Further, if you would like to try one of the premium tubes, to my ear the US-made Amperex 6922 is superior to my Bugle Boys and OG.
