Hello,
I have a 36.5 arriving next week and am in the Transporter Queue as well.
I thought it might make sense to start a tube-rolling thread. There is a lot of info on tube-rolling for both pieces scattered about here, but it would be really convenient to have some, most, or all of it reproduced here in a dedicated thread! Doncha think?
I figured combining impressions of tubes in both devices makes sense because:
- They both, of course, use the 5AR4 family of rectifiers and 6H30 signal tubes.
- A lot of people own both units.
I'm afraid I have little to offer at this point other than the start of the thread.

I have a substantial stash of tubes but nothing at all in the 6H30 family (if there is a family). I can attest that NOS Mullard 5AR4 equivs can do a wonders for a circuit.
Cheers,
Paul
