That only happens when you hold the cat close enough to feel the vibrations.

Ok. Completely confused. I think my brain's melting.

Mu --> mew --> purr --> vibrations --> holding cat close --> transconductance --> you feel the cat Mu-ing --> I'll shut up now.

It was a long day at work. I was trying to inject some offbeat humor.

I got it, I was just going for humor (fail). Didn't mean to confuse...

Hey guys. I just got my Aune and was considering picking up the Crack with Speedball upgrade. I ordered an Amperex OG for my Aune, so does this mean that if I get the Crack, I should get another Amperex for it? Should I use the same bulb for both or is it better to mix than match?

 

Thanks!

Doesn't really matter one way or the other.

There's really no clear path for you. Only your ears can be your guide, but sticking with the tubes that Doc sends you for a while is a good starting point before you start changing things for the sake of it.

doesn't the Aune use an E88CC / 6922,  ECC88 / 6DJ8 and not the 12AU7 / ECC82? I haven't got an Aune but a 12AU7 would be an odd choice for that type of circuit. If it is E88CC / 6922,  ECC88 / 6DJ8 I would not use it in your crack.

My Crack arrived on Wednesday and today I began my build! Starting with gluing up of the wood enclosure and prepping of the alloy plate.

 

Very impressed with the build manual. The speedball looks a bit daunting at first for this newbie so hopefully after building the crack I will feel a bit more confident. As I have never done any soldering before I am also going to need to do some practice pieces first before I get started.
