Hey ya'll! I have a new number 1 tube for my LP, and it is the Philips Miniwatt SQ E188CC 63'. This tube has the best bass I have heard with the LP, killer euphonically textured mids, and extended but never harsh highs. The bass is powerful, tight and deep, and the soundstage is huge with this tube, as well. The euphonic texture in the mids is insane, and you can almost touch and feel the notes in front of you. This tube is on another level, and really has that tube magic.

Interesting! I've heard other Philips Miniwatt tubes (although not in the Liquid Platinum) and I've found them to be too bright for my taste. I take it that you don't find the treble too prominent on these?

Miniwatt tubes can be Mullard, Heerlen, Hamburg or French tube manufacturers all with their own house sound.

These are Heerlen big O getters with grey shields and I am super sensitive to bright treble, and these are not harsh at all, but well extended. Perfection.

Hi @WhiskeyJacks,

Welcome to the tube rolling club!

The Arya are great headphones, I currently have the Ananda’s and really enjoy them.

For the “warning” of using adapter tubes. Anytime you use a tube that has different operating parameters from what the amp was designed for you run the risk of having the amp fail prematurely. This is not to say it’s a guarantee the amp will fail but a “slight” possibility. I have been running adapter tubes in my LP from the beginning with out issue and know of several other that do the same with out issue.

For My recommendations I would pick up a pair of socket savers first from Tubemonger these specifically https://www.tubemonger.com/NOVIB_Socket_Saver_1960s_NOS_British_McMurdo_B9A_p/novib-mcmurdo.htm
Though it looks like he just sold through, he should have more back in soon.

The reason for the socket savers especially for the Liquid Platinum, is the Liquid Platinum has an absolute “death grip” on the tubes, when I first received my Liquid Platinum (before I had Socket Savers) I installed the stock tubes listened and decided I wanted to tube roll. In the process of removing the stock tubes, I seriously thought I was going to break the Liquid Platinum. As the “death grip” is that strong, ever since then I use Socket Savers.

Recommendations on tubes is actually a very easy one for me now. I would get a pair of these tubes once he gets more in (2-3 weeks)
https://www.tubemonger.com/Mullard_CV3986_6021_1975_Mitcham_E88CC_SUB_NOS_p/ex-6021m.htm
I was the beta tester for these tubes and they are easily my favorite tube of all my tubes not just the ones I use in my Liquid Platinum. I also have the Schiit Mjolnir 2 hybrid tube amp.

I’ll post my impressions of the tube here, in the mean time here is a link to my review

[LP] tubes that will work in the LP

I have a question right now I am rolling with the "58 Bugle boy D getters and I really am enjoying thanks to TK16 for the link, btw. I have a question my adapter for the 396A/2C51/5670 And so on is in as well and socket savers. The LP you put next the Sub Mini Variants are they just the ones you tried with the Platinum because I have the GE JG-5670 3mica version coming in and it is suppose to sound great. And if you tried it with all the sub mini variants why did it only work a couple of them?

I had 2 pair of those GE 5670. I sold them almost immediately, quite harsh sounding. I hope you have a better experience.

I don't if you got the same ones I am getting, the normal GE-5670 is a toss up it seems some people like them for the price and others do not. the ones I grabbed are suppose to a better GE Variant. We will see

The ones I had were the military designation JG GE 5670 square getter.

I did not know there was a "better" GE tube. I have heard they all are so so. . .and based on what others have said I have not bothered trying them. The Tung Sol and Western Electric 2c51 tubes, are another story.

The other tubes with the 5670 adapters are the Reflektor 6N3P 58 triple mica. There is 2 pair available from the same seller 29.99 a pair.

No according a to a head-fiers I trust they like the 5 star triple mica version as much as they like the 396A for different reasons for a lesser price. I will see for myself and let you know what I think when they come in probably after the weekend. I am planning on getting the reflector tubes you linked to my TK16 I still have the link.

The other USSR tubes I have heard are even better than the Reflektor tubes are Foton 6N3P 3x mica 50's. Impossible to find. These are bit warmer than the Reflektor. The 60's Foton 6N3P are available on Ebay. Not quite as good as the 50's Foton's but quite cheap.

Nice! I look forward to reading your thoughts, once you have listened with those GE tubes.

Hi @WhiskeyJacks,

First off glad to hear you are enjoying the 58 Bugle Boy D getters!

The sub-miniature tube, are different from the 396A/2C51/5670. As the sub-miniature, are the Mullard CV3986/6021 this tube does work in the LP and you do not need an adapter as the adapter is part of the base for the sub mini. The Mini-Mullard is my favorite tube overall, beating out every other tube I have.

For the 396A/2C51/5670 variants, the ones that do not have the [LP] next to them are ones that are noisy in my LP, not saying that the ones you are getting will be noisy. just happens that mine without the [LP] are noisy.

Want to add that the 2C51/5670/396A has a higher amplifcation than ECC88 makes these more prone to noise in the LP. I have experienced this in the past and ceramic adapters are more prone to noise.

The tube rolling bug jumped up and bit me again! I have a pair of Sylvania 6922 d getters 63' on the way, and can't wait to hear them. I have it on good authority these are the tops for 6922 in the LP, and can't wait to see how they compare to the Brimar CV2492 and Philips E188CC.
