I should put my bare glass C3g tubes back in someday.

The HEXFRED adapters are not going to look as nice as the 6BY5s

Thanks. It's much better.

They really are better then any tube rectifier. People pay $1000 for a TAK 274B crazy when 2 HEXFRED diodes
cost $2.  Cary is getting rid of the 5U4s to HEXFREDS as a upgrade and they are much
better then any 5U4 or 274 no voltage drop or sag in voltage when the amp draws more current.
I prefer tube rectifiers but cheep ones I am not nuts yet to spend $1K on a 5U4 that could be spent on good 300Bs.

Great mod Tony!!!!!!!!!!

Tubes all the way, but at a sensible price.
With tube rectifiers you can change the sound with SS is a take it or leave it situation.
 
Saying that I have tube amps with SS rectifiers and I love them..............so it's all about the design and implementation.

  I plan on finishing my EL3N amp this weekend then I have a OTL to build then I will contact you.

Cool! Thanks Glenn.

Do you want tube 42EC4 or SS rectifiers.

I trust you, whatever you think is best.
I already have 2 or 3 pairs of PY500 but not a big deal if I don't use them. I will go with your recommendation, you are the guru!

Look like we need to show the community this, one of the reason I moved away from Woo is the rectifier cost, WA5 uses 2 5U4, so double the $1k+ for rectifiers if going for totl sound. Maybe @badas can order a hexfred from you for his wa22 to compare to the tak he got and post his impressions.

On tge 42ec4 vs ss, the only reason you're not able to make the ss adapters is the base right? Do you think we could sacrifice a set of 42ec4 and cut them open, carefully with maybe a copper pipe cutter, slowly grinding the glass down, then remove the internals and make space foe the hexfred diodes?

Owning a 300sei with hexfred rectifiers I'd say they produce a very neutral response letting the input, driver and power tubes really show through.

And if you have an amp that uses 5U4-type rectifiers, a HEXFRED from Glenn gives you the best of both worlds in one amp. Having choices is always a good thing, IMHO.
