Woo WA33 modded + all upgraded tubes (Takatsuki TA-274B, EML 2A3, WE 417A) + many extras


Price: $7600 obo
Currency: US
Ships to: CONUS

Selling my Woo WA33 (silver) in absolutely perfect condition. It has been modified with an RK50 volume control featured in the more expensive Elite version. This is my favorite HP amp/preamp of all time, but need to downsize.

It comes with all original packaging and accessories as well as the following upgraded tubes:

  • 1 Takatsuki TA-274B rectifier (bought new 2021)
  • 4 mesh EML 2A3 power tubes (bought new 2021)
  • 4 Western Electric 417A driver tubes (bought new 2022)
  • 4 custom made driver adapters and 4 extra spares
  • 4 Electro Harmonix driver tubes
  • 4 Sovtek driver tubes

So basically the best upgraded tubes for this amp, all with very low hours, and a bunch of extras for tube rolling.

Asking price covers shipping and insurance for all Cont US. Local pickup in Queens NY would be ideal (and offer a discount), but willing to ship. Would really prefer PP F&F because of new IRS extra cost. Wiling to provide feedback here, Headfi, Ebay, Audiogon, US AudioMart…

Feel free to contact me regarding any questions or concerns.


Not seeing the price?

My bad, it’s now been fixed.

It is absolutely none of my business, but I don’t know how you can part with this. Lol.

Lol I know what you mean trust me. Wish I could keep it but my budget only allows for so much and I have to fund other purchases…
