Very cool and of course I was being facetious. My son is amazing about keeping things I have given him, somewhere there is a Z car in silver that was very much like a Datzun 240Z I owned. I gave him a red Mazda RX7 when he turned 16 but he eventually totaled it. Now he buys his own sports cars.

I just gave my white one a bath yesterday. Still shines up pretty nicely for a 16 year old car, and I haven't totaled it....yet. Of course with its book value what it is today, all I'd have to do is break a headlight and it'd be totaled. :smile::smile:

Bill is just a teeny bit anal retentive, so that's to be expected. :smirk:

Maybe someone of you 6SN7 enthusiasts can answer my question.
According to this Website.
https://tubemaze.info/tube_equivalents/

6SN7 tubes can be used as replacements for 12BH7 tubes and only need an Adapter. (Octal to Noval)
In other words, they have different pinout but are electrically identical.

Has anyone experience with that and can confirm?

The 12BH7 is close to a 6SN7, a direct replacement would be the 6CG7.

It depends on what voltage your amp is running the 12BH7's at. The filaments on a 12BH7 can be run at either 6.3v or 12.6v -- if your amp is running them at 6.3v, then an adapter should allow a 6SN7 to be subbed (although it will have more gain). If your amp is running the 12BH7's at 12.6v, then a simple pin converting adapter will not work -- you'll fry the filaments of the 6SN7.

Thank you guys.
So I have to ask McIntosh at which voltage they run the 12BH7 in their new MHA200.

Do you think they will reveal such detail?

I would imagine the MFG would provide that information.

BTW -- if your amp is running the 12BH7 at 12.6v, you could run 12SN7s -- the 12v version of 6SN7. :wink:

Never hurts to ask. At worst, all they can say is they won't say. :smile:

@Ripper2860 's advice on the 12SN7 is also a good one. Good 12SN7's are usually much cheaper than 6SN7's mostly (assuming) because they aren't used as much and subsequently don't have as much demand. The only difference spec-wise between the 12SN7 and 6SN7 is the heater (filament) voltage, otherwise they are identical electrically.
