What's the BEST 45 tube and where can I buy it?

[WilliamLee]

Hi!

I am new with DHT tubes, and want to make my own 45 amplifiier. I heatd so many great things about this tube. Does it really sound better than the 2A3?

Who has experiences with this tube, and what's the best place to buy it? I heard a lot of good things about the Sofia (=Fullmusic??) 45. Is there a Fullmusic official website? I only found this one: http://www.fullmusic.de but why is it in Germany? THey show mesh and solid plates, but how about the sound? Is the Emission Labs 45 a good tube as well? Where can I buy it?

What is the BEST Single Ended tranformer for this tube... Where to buy it? Sorry for the many questions. I am in search for many answers. Please reply to this post when you have some information about the 45.

Thanks!!! William Lee, Hong Kong

Dear William,

Opinions vary on the "best" tube... but the 45 does have a very strong following. I have built a number of 2A3 amps and nothing has come close to my 45 amps even though the circuit topology was similar.

Try http://www.diyhifisupply.com in Hong Kong for FullMusic or TJ 45 tubes; I am not affiliated with DIY Hi Fi. Emission Labs is also reported to be good. However, 45 tubes are often available through ebay at good prices... but "cavate emptor" (buyer beware)!

There are several great transformers for the 45 tube:

Magnequest ES-050 air gapped
Magnequest EXO-050 parafeed
Tamura F-5003 amorphous air gapped
Tribute also sell transformers for the 45 tube

Remember, you will need effecient speakers; many say at least 96 dbl but I would suggest at least 99 dbl.

Good luck with this great tube.

Hi William, Hi Seta 45,

yes i bought the Emission Lab 45 Mesh tube from www.jacmusic.com . These tubes kicks ***! They are way better than anything i heard from NOS 45 tubes.
For this EML 45 Mesh tubes i recommend lundahl iron's.
I also bought the Lundahl from JAC at Jacmusic.com
....very fast delivering also best prices....

You would choose the Lundahl LL1663/50mA -----5K @50mA
or the Lundahl LL 1620/60mA ---- different impedances
If you have more questions about schematics feel free ....

Greetings Barossi

A friend has a DRD 45 amp and his 95 dB speakers don't really cut it...
