Adapter is definitely easier but better not to introduce any connectors, on the long run the phone cables won't be happy going upwards and curved

I agree on adapter. But the can I use on the amp is xlr terminated. If I did add the SE plug it would face out, not down. That was my initial idea. But out would be difficult to make solid enough for trouble free use.

Agree

Which tubes exactly am I able to use in the Crack. Seems I can only use 12AU7 (at least without any adapters) in the front socket but what about the rear socket?

421A, 5998, 6AS7G, 6080, 6520, 7236 in the rear socket.

In front don't forget ECC82 is the same as 12AU7.

E80CC and more

 

[HTSkywalker]

Probably a 6SN7 in the front is the best bet

Just to clarify. I was asking what types will fit the stock sockets and won't require any adapters.

and yes the 6SN7 would require an adapter

Well a E80CC is a 9 pin that fits. But use it with Speedball and a resistor value must change. The makers have a list in the doc that comes with the kit. Also Google E80CC and 9-pin and visit the list from AliExpress.

From what I can find the E80CC is pretty pricey. I wonder if these would be any good?

Yeah it's not cheap to obtain. I think you get a very clean sound that has dynamics and the liquid magic.

I would get the exact specs. The key one IMO is ch balance. Finding max versions in matched pairs is a major thing - thankfully for this application it does not matter.

My estimate is 75% of these tube dealers are frauds. In particular eBay guys. I like Brent Jesse's. His reviews are worth it alone.

I saw a pinched waist E80CC matched pair for $7500. Yeah sure..

Crack OG (no speedball) is amazing. Took down amps I have that cost 10x more. Its truly a magic machine. I prefer OG to speedball version (I have both).

It is very warm, fluid, 3d while still rendering detail very well. Excellent imaging and space.

If by OG you meant the original standard version vs the Speedball added then that's a first.
But again YMMV situation

Even Justin at ampsandsound said he prefers no speedball.

I think a lot of people just just jump right to speedball without really trying og or having og and speedball next to each other to compare.

All of the 12au7 types will fit, such as ecc82 and 5814a.

E80cc will fit but won’t be optimal without small internal changes. Same thing with the 12bh7 tubes.

You can find adapters online for tube types like the 6sn7.
