2x ELECTRO HARMONIX 12AU7/ECC82 and 2x TUNG-SOL EL34B.

[1980Nicola]

I have an Unison Research Simply Italy amplifier, which originally comes with 2x ELECTRO HARMONIX 12AU7/ECC82 and 2x TUNG-SOL EL34B.

I replaced the ELECTRO HARMONIX 12AU7/ECC82 with MULLARD NOS 12AU7/ECC82 GF1 B and achieved a much warmer sound, I’m really satisfied.

Now, to complete the path I’ve started, I’d also like to replace the TUNG-SOL EL34B, which sound quite neutral. What could I replace them with?

EL34 NOS tubes are insanely expensive, so I’d rather skip those and go straight for current production.

What would you recommend? I listen exclusively to Jazz, so I’m looking for a warm and enveloping sound.

Thanks for your advice!

What can you tell me about the PSVANE TREASURE EL34-Z? Could they be a good choice for a warmer and more enveloping sound?
