A WA6SE will be excellent for HD650 and the MAXXED upgraded 6SE will be excellent choice if $$$ permits...

I disposed all my previous 6DE7 & 6EW7 tubes couple of months back with regrets as I was exploring the 6SN7 option on my WA6SEM. The idea of using various 6SN7 tubes via adapter was dropped almost immediately and rolled back to the stock GE 6EW7 supplied by Jack. I just received a pair of...

For those who needs a pair of Glenn's adapter for their WA6SE may reach me .... I have two (2) kept in the box.

Yup, just desolder the stock caps and solder the upgraded caps. Quote:

These are the enhancements made to the Havana:   * HiFi Tuning Slow 400mA small Fuse for MHDT Havana * V-Cap OIMP 2.0uF/250VDC for MHDT Havana   The units were perfectly in great working conditions before the mod.   Quote:

I can only tell that I loved my modified Havana.... It was just a simple mod of the output capacitors and fuse..

Yes, It can be done with a small fee. Quote:

My WA6SE was made last year and that could be the reason why I am benefiting from 6SN7 selections. Despite the the modifications made by Glenn for WA6SE, I still don't find any excitement> I am on the stock 6EW7 supplied by Jack, United Electronic with the Sophia Princess 274B.   If you need...

It may suits many but not too my likings after all. It was kind of weird experience with 6SN7s or VT231. I find it too much distortions with those tubes.

I am done with the 6SN7 options for my maxxed WA6SE. All the tubes were sold and switched by to the stock 6EW7. Anyone who needs the Glenn's adapters which contact me.

Quote: One of them is bad so I returned the pair.

I received a bad pair od SG CV181-Z on Monday. Return to seller for refund.

Quote:   That is not encouraging, my CV181-Z is schedule to be delivered on or before next Tuesday. I read somewhere that is requires approx 300 hours to mature the tubes. Guess that 25 hours ain't enough, do report once it reaches 50 hours. Keen to know the outcome while waiting for...

I bought a matched pair of ShuGuang Treasure 50 years CV181-Z as a 6SN7 replacement for my WA6SE. It is being shipped now and arriving in the next couple of days.. Can't wait to try it out and I pretty sure it needs some time to burn in before hearing any refinement.

Quote: Nope, just opt for the standard match pair..
