Chiliarches Posted April 29, 2019 Share Posted April 29, 2019 Howdy, all. I picked up a Chinese FTLYS EL34 SET amp and I am really enjoying experimenting with it on my Cornwall 1.5s. It sounds nice - airy and with a nice soundstage. I am honestly shocked at what I got for $260 with free shipping from Amazon Prime! https://smile.amazon.com/gp/aw/d/B07MD74G92?psc=1&ref=ppx_pop_mob_b_asin_title The amp came with stock tubes that were branded FTLYS...unsure who made them. I would like to role some tubes to give it a richer, “plummier” quality, with more bass / tonal weight / bass slam. The tone is a bit too light/glassy for the kind of music I listen to at the volumes I listen to it. What would you suggest? I understand the amp has limitations due to the design, but I have heard amps of comparable wattage with much more “richness”, so know it’s not just a matter of power. It’s a $250 amp, so not looking for $300 tubes, looking for a “value” suggestion... Thank you!!! Quote Link to comment Share on other sites More sharing options...

edmjm Posted April 29, 2019 Share Posted April 29, 2019 for more slam & authority to the bottom end I’d suggest electro harmonix 6ca7’s. but the trade off is I’d call the top end as more accurate than rich. they are a direct replacement for el34’s 1 Quote Link to comment Share on other sites More sharing options...
tube fanatic Posted April 29, 2019 Share Posted April 29, 2019 There is no way to predict how a particular tube will perform in your amp. The only way to know is to experiment and draw your own conclusions. Maynard 3 Quote Link to comment Share on other sites More sharing options...

Danieln Posted April 30, 2019 Share Posted April 30, 2019 I suspect the output transformer is more probably the cause instead of the tube itself. Not enough primary inductance will cut into the bass. 1 Quote Link to comment Share on other sites More sharing options...
