Are those required adapters approved for use by Lampizator? There have been some inferior quality ones that could hurt performance or the device. Whose are they manufactured by?
They are manufactured by us. I’ve been using them for a while without any problem. A lots of WTB members and some Lampi dealers also use them.
The ECC40 tubes sell for $40-50 each for Tungsram and Philips up to $150 to $500 for rarer versions. The E81L tubes are generally really inexpensive at $10 each. The AZ4 rectifier is generally $25 to $30. Are these the low cost alternative tubes that are superior sounding with adapters in the Poseidon or the more expensive versions such as a mesh plate AZ4 which is rare and very expensive or the high end Valvo or mini-watt Philips ECC40s?
With better tubes Posseidon will sound obviously better. This is just an example that you don’t have to spend a fortune to make superior sound. Compared to the stock tubes the difference is huge, like having a totally different dac.I like the ability to purchase more common and inexpensive tubes. The ef802 sells for $3,000 to $6,000 for a set of 8 and one Valvo G2504 for $2,000. For wealthier folks. I chose the Westminster Labs REI as sounds as good as any tube amp I've experienced but solid state/no tubes. A 33,900 investment good for decades.This the low cost version
I’ve tried the Posseidon with ef802 tubes too (you need 8) and Valvo G2504. With them another big jump.

then take ef804s if you like that pentode sound, they are in the best studio amplifiers in the world. you need a double noval 9 pin socket. the ef 802 is much more expensive because it is popular for neumann microphones, every musician or recording studio wants it because there is no alternative.

I’ve tried both tubes. The ef802 was clearly better.then take ef804s if you like that pentode sound, they are in the best studio amplifiers in the world. you need a double noval 9 pin socket. the ef 802 is much more expensive because it is popular for neumann microphones, every musician or recording studio wants it because there is no alternative.

This is only due to the inappropriate working point of the device, otherwise the race would have ended differently. Trust me.
