Would like to know best tube sources for my LL2.1 preamp and LP2.1 phono since Lamm does not have anything resembling customer service.

Lamm works through their dealer network. Have you spoken to your Lamm dealer? There are several here on WBF including Steve Williams, (@Steve Williams) David Karmeli (@ddk) and Gestalt Audio (@gestalt). If you are polite I'm confident a dealer will be able to help you. I"ve found Lamm has excellent customer service if you give them time to get back to you, as noted here: Contact Lamm

LP2.1 Tube Complement:

Other than the rectifier tube, V101 - V104 are Russian tubes. You can find them for sale on ebay. If you want them tested and matched, then Lamm or a Lamm dealer with stock is probably your best source.

V101 -6C3P / 6C3П, left channel, first amplification stage;
V102 – 6C3P / 6C3П, right channel, first amplification stage;
V103 – 6C45P-E / 6C45П-E (original), left channel, second amplification stage;
V104 – 6C45P-E / 6C45П-E (original), right channel, second amplification stage;
V105 – 6X4, full wave voltage rectifier.


LL2.1 Tube Complement:
These are very common tube types. You should be able to find examples from most tube dealers.

V105 – 6X4
you can use: 6X4W, 6X4WA, 6202, EZ90, CV4005, CV493

Left and Right channels each take one of the following:
V101 – 12AU7A
you can use: 12AU7, 12AU7WA, ECC82, E82CC, ECC802, 5814, 5814A, 5963, 6189, 6680, 7730, CV491, CV4003, CV8155

V103 – 6DJ8
you can use: 12AU7, 12AU7WA, ECC82, E82CC, ECC802, 5814, 5814A, 5963, 6189, 6680, 7730, CV491, CV4003, CV8155

Note: changing tubes in a Lamm preamp may require an internal adjustment, eg via a potentiometer, using a voltmeter. Lamm can provide specific instructions if that is needed for either of your models.

First of all....

When I wanted the Lamm shop to do an inspection/check-up of my LL2.1 last Summer, I did go thru my local Dealer, Jaguar Audio.
Here is his response:

"
Hello Rick,

You’ll need to contact Lamm.

Regards,

Darin"

It was weeks before I my emails were finally answered by Elina... and only because someone who purchased a lot of gear from them, contacted the company and mentioned that I wanted my preamp checked out.


I also inquired to Jaguar Audio about tubes and again, when I told them I could not reach Lamm:

"
Hello Rick,

I'm sorry to hear that. I don't have tubes for these. I would take some pictures of them and post them on a tube forum. You'll probably encounter someone who can tell you what they are and where to find them pretty quickly.


Best regards,

Darin"

Yes, I already have referenced the FAQ tube information from the Lamm website
Also from the Lamm website:

"We recommend ordering 6C3P and 6C45P-E tubes from Lamm ONLY, as we perform tube selection for each LP2.1 phonostage based on identical tube parameters, and that assures the identical behavior of both its channels. Our in-house designed and built tube testers allow us to measure four different parameters of each tube (in contrast with commercial tube testers that measure only one parameter). Based on gathered data we test and match the tubes with unsurpassed precision that simply has not been available before."

My owners manual has the factory individual readings for each of these tubes, specific to my LP2.1
and states that Lamm matches each as close as possible.

last Summer, I did go thru my local Dealer, Jaguar Audio.

I understand - I've had both models in my system. Although the Lamm Web site lists them, the jaguaraudio.com Web site does not list themselves as a Lamm dealer - it sounds like twice they passed you back to the company. I suggest you check with an active Lamm dealer for a different level of service.

I was thinking of testing out some different rectifier tubes in my LP 2.1. Would I be safe using any of the following tubes: 6X4W, 6X4WA, 6202, EZ90, CV4005, CV493?

Also, any opinions on what the best 6x4 for this phono stage would be?

Thanks!
