Depends what headphones - the RCA is an average all around rectifier - nothing amazing and at the same time generally under rated for the value. Clean sounding (somewhat less warm) and not as sweet as others...I personally prefer the RCA (in my chain) with Grados and paired with Sylvania Bad Boys (6SN7s). Although, I'd grab a Philips 5AR4 (Sittard), Brimar CV717 (KB/FB), or USAF 596 ahead of it anytime.

its s

they are asking $115

You can get RCA 5U4GY from Watford valves in UK for 10 to 20 USD.

Not sure how similar they are but thought you should know

I really enjoy it. It's very good for what you pay for imo

I agree with @David222 on the RCA 5U4GY. If you want something special (airy, dynamic, extended, full-bodied…) for a reasonable price, get this. [I use this as my ‘baseline’ rectifier in Woo WA6.]:

Better to decide soon while GBP to USD exchange rates are low.

Another vote for this one - great little rectifier!

Looks great...Enjoy!! Let us know when you're ready to swap/upgrade the fuse (down the rabbit hole you go). :stuck_out_tongue_closed_eyes:
Don't corrupt the boy (yet). Let him get totally hooked first. Then it's like heroin. Only more expensive.
