I’ve been using the stellia with the echo2 but I only have stock tubes. I don’t know much about tube swapping. What tubes have you put in yours and where did you get them from?
Thanks
Gaz!
Hi Gaz,
I’m very much self-taught and don’t know much either. However, I’ve done a bit of research online to figure out:
1) what types of tubes are technically equivalent to the Echo stock tubes
2) which ones have what characteristics
3) what general prices are
I started out wanting to have spares in case the stock tubes failed. Once I had those (Gold Lions, which were not very expensive and purchased through Upscale Audio), I started learning more about equivalent types, quality etc. About $ 300 USD later
I have four different additional sets, so I have tubes for years- all very good and with a bit different sonic characteristics. It’s been fun!
After buying via Upscale the first time (and knowing there is a bit of an upcharge for the service, tube testing etc.), I became more bold and purchased through the classifieds here, which was great. I may have also bought a pair through US Audio Mart, also a good alternative.
The key is to check with private sellers if the tubes are matched, how many hours are on them, and make sure through research if they are the ones you want/need.
The ones I’m using now in the Echo are new old stock (1960s) Amperex, I forget the model number offhand, but it’s below in my signature. I’m currently traveling, but please let me know if you’re curious about the others I have and I can post a list.
