PorkBun69s Posted July 4, 2011 Posted July 4, 2011 Hi guys, Just want to get a general consensus on some 300B tubes. I've been looking at some TJ's / Sophias but am unsure of the improvements of those carbon plates vs mesh plates designs. Value for $ i guess would be the mesh plates. Your opinions please..
ehtcom Posted July 4, 2011 Posted July 4, 2011 (edited) It really pains me to say this as I love the TJ mesh plate globe. I've had a few issues with the reliability of the TJ mesh plate 300B and am now supplying Shuguang 300BS globe tubes with the TM300B. So far out of ~30 pair I haven't had a dud. the mesh plates work really well in the TM, didn't like the carbon plates, they seemed a bit bright to me. Cheers, Earle. Edited July 4, 2011 by ehtcom
PorkBun69s Posted July 4, 2011 Author Posted July 4, 2011 Thanks guys. Thats really helped with my decision.
Guest Posted July 5, 2011 Posted July 5, 2011 Hi Kat I would go with KR ,EAT or even the EML's I haven't heard the EML but I would say their similar to the VIAC tubes .Build quality is in another league over the chinese tubes and with this come SQ . One day the Chinese might make a true Mesh plate . The Shuguang tubes are good value compared the the TJ's if they sound the same or similar go the Shug's . Cheers
Guest guru Posted July 5, 2011 Posted July 5, 2011 afternoon 56, i tried some eat 300b tubes the other day and wasn't overly thrilled. got a client who wants to try the sophia royal princess 300b's but wants me to bring them in if he doesn't like them at $1200. i'll let you know how it goes. cheers, g.

Hi G There a nice tube down on power over other 300B's ,I find them similar to a 2A3 sound wise but there well OVER PRICED I wouldn't be buying another .One thing you need to make sure the plate voltage's are spot on and biasing someone I know found this out .You should be able to get them just under 1k a pair .I still like my KR's one day when the dust settles on the build front I might get a pair to try . Cheers

Cheers Hi Oval, Saw your reviews on the KR Baloons from 2008! They do sound like a nice well balanced tube. Seems hard to find though, as PartsConnexion dont seem to stock them anymore.

Email KR for price and supplier ,the ST & Balloon are the same performance wise but different glass envelope's price up to 1K a pair. Cheers

Hi Earle, In your opinion, do you think the TJ Mesh plates or Carbon plates sound closer to the EH 300b gold pins? I have the EH tubes in my Time Machine atm. They sound well balanced (lows and mids) but the highs seem recessed IMO.
ehtcom Posted July 13, 2011 Posted July 13, 2011 Not keen on the carbon TJ's in the TM. They sound thin with no body IMO. Go for the Shuguang 300B in the pic above. IMO they everything the TJ's are. You will loose a couple of watts output and also a little bass, the mids and highs are where you gain. Cheers, Earle.

PorkBun69s Posted July 14, 2011 Author Posted July 14, 2011 Article dated 2002...out of date now I reckonVanch... For sure. But i reckon the info at least on the EHX tubes are pretty spot on IMO.
georgehifi Posted July 14, 2011 Posted July 14, 2011 http://www.svetlana.com/ProductSearchResult.aspx?Srch=300B and much cheaper if your a member, for memory the last time I bought off them it was around 33% cheaper, and fast postage. Cheers George
