If you just want a replacement stock tube you can find them on amazon, a few sellers offer them with prime shipping. have you back and running in no time. If your looking to experiment, have to read the thread, there's many options.

Thanks Peeps,
I appreciate it!

Was running '75 SWGP Reflektors in the LP for a while to pair with my ZMF Verite.

Tonight, i decided to roll some tubes and listen to my LCD-3. The Brimar E88CC was quite a nice starting point, but I wanted more bass still with the Audeze.

Settled on WE396A on the LP fed from my Freya pre-amp with Tung Sol VT231 BGRP in gain and Mullard ECC33 in output slots. Amazing pairing with the LCD-3

@UsoppNoKami, How does the Cayin HA-1A Mk2 compare to the Cavelli LP in SQ and tube rolling options?

Very good looking piece!

The Cayin HA-1A mk2 lets the character of the tubes rolled really come through. Can go from a fast dry sound to a really wet organic tone or anything in between. I love the Cayin with the tubes that I have collected, but it is relatively more sensitive to picking up things like AC noise so you have to put some good power solutions in place. I have it set up to pair with my HE1000SE, while the Liquid Plat runs the LCD-3 and ZMF Verite. The latter also sounds good on the same WE396A tubes, but fitted with flatter pads (I'm running the unlisted ZMF 'BE' type pad) or the suede version of the Universe pads. Found the stock leather universe pads with WE396A too bloomy for my tastes.

So I finally got those Brimar CV2492's in. Been burning them in for about 15 hours and finally put the headphones on.

Ya, these are reaaaaal good. Will comment more as I spend some more time with them.

What are your thoughts on the Brimar’s now?

Still with WE396A in the LP, swapped out my TS BGRP & Mullard ECC33 in the Freya to run Telefunken smooth plate 12au7 gain and Sylvania 5692 output tubes. Details galore and a lot of air, whilst the WE tubes maintain the punch and prevent the sound from becoming lean. Nice combo with the ZMF Verite

@UsoppNoKami, Thank you very much for your second followup post describing the Cayin and LP in more detail! I decided to order the LP as it will primarily be used with Ether 2 and they can use a bit more power.

You have some VERY fun audio gear!!! I had to do a search for 'Rooms' headphone stands after seeing yours in these photos. The adjustable version you are using looks like it might be worth the cost difference.

I haven't heard the Ether 2 personally, only have the Massdrop Ether Cx. Depending on your music, preference in sound sig & what the E2 cans actually sound like, based on what I have read my guess is that Ether 2 will probably like similar tubes to the HE1000SE on the LP.

I have rolled the following in the LP:
E188CC Philips SQ by Mullard
Brimar E88CC
1975 SWGP Reflektor
Tesla E88CC crossed swords
New prod Gold Lions
Western Electric 396A
Amperex USA 6922 orange globe

Of the lot, the two I like best with the HE1000SE:
- WE396A. These have the biggest 'heft' to the sound, not just in bass but every note. A thicker body to the sound, more engaging.
- The Philips/Mullard E188CC. These have sweet female vocals, great highs but IMHO this doesnt like anything remotely rock related with headphones that are really revealing

The amperex USA 6922 orange globe gets an honourable mention from duty in my Massdrop CTH, may not be the best at anything in particular but has a fun sound signature, very listenable.

I also have 12au7 to 6922 adaptors and a huge collection of 12au7 tubes from the Cayin amp that I could roll in the LP as some here have done, but I prefer to pick a baseline with the LP tubes, then fine-tune via the Freya tube pre-amp. A/B is very easy as I can go from passive/active to tube stage in a couple of button presses.

Note on WE396A - the US made HQ adaptors didnt work for me. Mrs Xu's did. I also had to buy 3 pairs of WE396A before I found one pair that was quiet enough in the LP. The other tubes worked fine in tube buffer output stage of a DAC, but just too noisy for the LP.

My current favorite tubes are the Seimens A Frame E88CC. They are very vivid, mid forward and have an open soundstage.

What they seem to lack is some bass impact.

Do any of y’all have recommendations on a new pair of tubes that have great clarity/vivid details but a little more oomph in the bass department.

Just ordered the Tungsram PCC88 / 7DJ8

Can't wait to get them and test things out.
What is the average break-in period (if any) for tubes of the sort?

Thanks

If they’re NOS, nothing less then a 100 hours but that’s not enough time IMO.
At 200 hours? You’re there. If they’re new, you shouldn’t need any burnnin unless they state they’ve hardly been used.
Actually, you can get a good idea right away. Tubes definitely change, but by no means night and day. Some may disagree but that’s what I hear. Good luck.

 

[glitch39]

and he mentioned 6CG7 tubes... according to him:
"It's a 9-pin version of the 6SN7, and is pin-compatible with a 6922 (no adapter needed). Amplification factor of 20. Only thing is that it pulls 600 milliamps of heater current versus 300 for the 6922 (the 396A pulls 500). Can the amp handle the higher heater current? Sounds like it handles the 500 milliamps for the 396A..."

Tried and confirmed no go on my Sylvania 6CG7's.

Can you use PCC189 as a drop in replacement? from the below site it seems like you can.

http://www.audiotubes.com/6dj8.htm

But I wanted to see if anyone has tried.

Yep, love me some Siemens PCC189 tubes but the Telefunken PCC189 were too polite and a bit boring. The Siemens PCC189 are buttery smooth, clear and rich and they pleased me more than any of the 6922 variants I tried in my LP (including Telefunken E88CC or ECC88, Amperex whilte label USA 7308, NOS Mullards, Brimars, Tungsram, et al). Maybe someday you will be bold enough to try 12AU7/ECC82 tubes with adapters which you may like much more in your LP than any tube from the 6DJ8/6922 family.
