Hi All,
I got my Wavelength 300B integrated up and running thanks to Scott Frankland's shop, and it sounds great, except that I seem to have an intermittently microphonic WE 300B. Some days it's dead quiet, others...not so much. Is that really possible to have one intermittently microphonic?
So, if I need to replace them my realistic choices are the EH Gold, or the Genalex. Price difference is about $100, so no big deal. Any rec's on either of those, or any others that are "affordable". No way can I get another pair of WE's, so substitutes will have to do for this amp.
Follow Ups:
Gen, EH Gold and JJ. All more or less the same price. Keep seeing JJ referenced as "rugged". Looked up to see if Gordon had anything to say about it. Said JJ was OK, but last message he was looking for something special. Never answered if he'd found anything. Maybe now the WE is producing again...for $$$ he went with them. Wish I could.
over many years I had a couple tubes that would do the same and tried resoldering the leads inside the pins - just a pinch. Assembly lines aren't perfect and once in a while something slips thru QC.
It could also be a weld on the connections inside but nothing I know of can fix that.
Never came across an intermittent microphonic output tube. But sorry to hear, and hope it's not the WE 300B causing it. I also have a pair of WE300B's in my amps, one of which have a loose base but, knock on wood, still works fine.
Regarding reasonably priced new 300B's, you can also look into JJ - still have a pair that is strong after many years and sounds great. The JJ 300B's have a nice heft to the tube with the thick glass and ceramic base.
I have no heard the EH Gold's, but besides the WE's, I have various Chinese ones (Shuguang Treasure, Sophia globes, etc.), the JJ, and the Genalex.
Personally I would go with either the JJ or Genalex. Good luck.
It is very simple to fix loose base. Have done it many times.
Read the second section of this post here:
Thanks, have tried previously with crazy glue and didn't do a good job and left some residue at the interface - it appears that only the top lip of the base comes into contact with the glass. Perhaps I can try again with the method described, but since the tube is working fine as is I don't want to touch it.
Using glue is very messy and ugly. The method I used is clean, just simply wiped off the excess of nail polish remover along the gap. One thing though, before baking them, just give perhaps a minute for the remover to work its magic in softening the cement. When all is done, you cant even tell.
I had them in my Cardinals for years. Built well, sound OK, good bass.
I never cared for EHs. People seem to rave about the Genelex 300Bs, but I haven't heard them.
