Used pair of Mullard CV2492s. I bought them a few months back from tubemonger.com. They are used tubes, but test very strong and sound incredible in my Woo Audio WA2. Simply the best I've heard with this amp. I've since moved on to the WA22 and no longer need these tubes.
Not really recommended for the Schiit Lyr as they did hum a bit with that amp...but are dead silent with my WA2.
Priced to sell at: $SOLD + shipping. (US / Canada only...confirmed Paypal addresses only too).
