    Can I run a 5Y3 in my goodsell s17? It has a 5U4. Has anyone tried this? What does it sound like?

    You can...at least for a while. A 5Y3 may be underrated for the job but a NOS tube will still last quite a while.

    You'll get lower volume compression and breakup.

    Sorry...the original is a 5v4 and I want to try a 5y3. I noticed on the website a 5y3 is optional.

    The 5y3 is ideal - my favorite - if you can get an NOS USA version. The Sovtek/EH 5y3s all rattle, making customers think there is something loose in the cabinet, so I had to quit using them. The 5v4, which is less common, was the only reliable option from my supplier, though it runs at a slightly higher voltage. The 5y3, the lowest v/a of the 5v recs, can still supply nearly 200% of the current required in the S17.

    The 5U4 will work fine, but the bottle is so large it is ungainly. The 5AR4/GZ34s commonly available new, are GARBAGE. Stay away from those unless you spend WELL over $100 for NOS Western Europe or US.

    I'd put a Phillips/Sylvania 5Y3 in every S17 if I could...

    I would toss any new production rectifier tube in favor of a NOS, the NOS are so much more reliable.

    The vintage Hammond iron in some Goodsells were designed for use with a 5Y3GT (The NOS 5Y3GT's about the same price as new ones).

    A used Mullard GZ34 is a great investment.
