Aimiya T9 Pro vs AIYIMA D03 - Tube life and availability in India

[tvnoobhere]

Hey Folks,
I had created a thread earlier for a budget 2.0 system powered setup, based on one of the suggestions I am trying to go with Micca RB42 + a Class D amp.

I am bit confused between the T9 Pro and D03, and the reason is the tubes.
How long do these tubes typically last? I believe the T9 Pro uses Jan 5725.
And how is the availability and cost of replacing these in India?
If its going to be a hassle, I might just go with D03, even though theoretically the T9 Pro should have the warmer sound that I wanted to experience.

And yes open to other recommendations on amps in this range, bluetooth + optical is needed for my use.

Edit: Had gone through some threads about tube vendors, however wanted to understand the approx cost and life.

Thanks!

if you can buy from abroad, you should be able to get soviet tubes - i read 6k4 may be a match (please verify)
I have a few tube buffers (little bear P3, fx audio tube 01,02 and 03) - all running russian tubes (6N1P - EV, the extended life version), and they have all have been running fine - the P3 is from 2015, the FX audios are from 2018

Thank you for the comment, I believe the vendor says 6k4 should work.
@greenhorn abroad = US - Ebay?

ebay.com, but not necessarily us sellers . I've bought from ukraine/eastern european sellers who ship old soviet surplus tubes to india at reasonable rates
