100 VDC plate voltage is okay for 12AU7, it's within normal operating points. As long as it's not 200+ VDC, nothing to worry about with regard to life span.

FYI, the plate voltage in Crack is 90 VDC, where the circuit is designed for 12AU7.

That's great news! I don't have to worry about damaging my prized 12AU7's. Thanks for the clarification man!

Yes, 200+ VDC would be running the 12AU7 really hard and shorten their life.

Received my adapters from @Deyan today. I had him build me some tall ones which are easy to remove. Time to roll!

LCML, you will be very happy with the new tube options you now have available!!!

Yep, I’ve got 5 pair to try out — paid less for all 5 than for my pair of CCa.

BTW, someone asked which board revision I have — there are holes in the sockets, so it’s the ‘new’ board according to @ksorota

Nice man! I would love to see a pic of those adapters in the LP. Which 5 tubes are you gonna be rolling in those, by the way?

Finally got the pc up and running, got the pair of 7316 LP D getters in I got a month ago. Sound fantastic.

Nice man! I would love to see a pic of those adapters in the LP...

Sure, I can put up a pic tonight. @Deyan recommended 40mm height, but I asked for 50. Turns out 40 would have been fine as you will see. BTW, with 'Covid-delayed' shipping from Europe, they took about 3 weeks to get here -- ordered on the 8th, shipped on the 11th, received on the 30th.

...Which 5 tubes are you gonna be rolling in those, by the way?

A couple pair Sylvania -- 6189 & 5814A
1 pair each Brimar CV4003, Raytheon 12AU7, GE 12AU7
Mostly around $30/pair, although the 5814A were $40 and the Brimar were $70. Total was slightly less than the $200+ I spent on my one pair of Siemens CCa.

I had a quick listen last night. I pretty much randomly chose the GE 12AU7s for the inaugural run. Note that I only had a short listen, with one set of cans (RAD-0), and the tubes had 0 hours on them. In addition, I'm still getting used to the effect the cap-mod had on the amp. As a consequence, I won't say anything definitive yet.

Well, OK, maybe one thing: the sound was quite pleasing. Certainly not like swapping in $30 tubes degraded the sound. Specifically, pianos sound quite natural, even 'liquid'.

I'll be rolling around this weekend, so I'll post some more soon.

Nice man! I can't wait to see those adapters, and my money is on the Brimar CV4003.

 

[Deyan]

There they are

Nice! Might order a pair too... I have adapters from long ago (before @Deyan came into our lives) which are very short, work great with the socket savers, but after re-cap I might abandon the socket savers, so would need the tall adapters

For my last order from @Deyan (adapters for a different amp) - I opted (per Deyan's suggestion) for a more expensive DHL shipping. Took 3 or 4 days (to California)!!
Was well worth the extra money!

I don't remember what the price was in that particular order. But since a month ago I am a corporate customer of DHL and for the same 3-4 delivery it's only 25$.
