Greetings! I do not have the L-07M monoblocks, but the L-05Ms. Hope this evaluation is of any use to someone looking for a preamp that make "magic" with these L-05M. I will choose always the Luxman CL-30 (tube amp) over L-07CII or Accuphase C-222. I have experimented with all three preamps...

YAMAHA C-1 and Victor JM-S7. You can't go wrong with this combination. I must admit, I admire your pursuit exclusively for V-FET amplification. Wally, I see that you also have the Trio L-07M mono amps. How do these compare to the B-3s in BTL mode? Are they better?

Greetings to all! I am always delighted to read your comparative impressions regarding the YAMAHA V-FET power amps. As I told you in my previous posts, I was piloting my first B-3 with the laptop at first which has caused a few issues, and a Luxman L-5 with full recap. The B-3 and L-5 made a...

The NS-10M monitors are leaving. The B-3 will never leave. I am sure I will buy them again in the near future, loved the sound of these small but wonderful speakers.

Any experiences with the Accuphase C-240 preamplifier from 1979? Back in the day it was the Accuphase top preamp, costing 400000 yen, until C-280 was launched in 1982.

noviygera, congrats for your B-3. I am looking forward to hear your impressions regarding the sound comparison between B-3 and B-2. What are the speakers and the rest of your equipment? P.S.: rottalpha has the best from golden age of YAMAHA in that picture, although the picture can be improved...

Exquisite restoration, zaibatsu! Congratulations and thanks for sharing your hard work with us. Please let me know how do they sound now? Looking forward to your impressions.

I like them alot, especially what sits on top of them. Have you concealed any power amps inside those stands?:D I am up to listen to my YAMAHAs, right now Allan Taylor - Beat Hotel is performing. Still in China, so here is GMT+8 hours, daylight.

rottalpha, yeah you have a tough first day of the year... I do not want to be in your shoes.:) I wouldn't know which one I should listen first. Now you are making me search for those beefy STAX monaurals. Where are the BX-1s and how do they compare to these STAX beauties? Tell me more about the...

Happy new year, dear friends! YAMAHA B-3 and NS-10M monitor speakers make a very good match even without a proper preamp and CD-player. The next test will be with the Trio L-07CII preamplifier and the B-3s in BTL mode driving the NS-1000M speakers. I am looking forward to this for years...

Greetings, Wally! I have the smaller brothers Trio L-05Ms and the Trio L-07CII preamp (all on 100V). I was unable to find enough time to listen to this combination (with my YAMAHA NS-1000M speakers) to have a final and clear verdict. I have listened like 4 year ago to Trio L-05Ms and YAMAHA...

If only I had 10k to spend I would buy these Luxman C-7i plus B-10 power amplifiers. In addition, I will insert into the basket a B-3 V-FET power amp. Sorry, YAMAHA, you got way to greedy this time with your M-5000...

These L-08M amps are also on my short list, Connor! Found a set of these in China with the external supplies L-08PS. Also a friend of mine in Romania has the whole set, including the L-08C preamplifier, this time on 220V. Looking forward to see your restoration and your thoughts regarding the...

It depends on the market. I can buy not one, but many C-2X preamps, 100V, with approximately 900 USD. However, at this price there are also Accuphase C-200X, Accuphase C-222, Luxman CL-32 (tube preamp) or Luxman C-06. I know that the C-2X is a masterpiece, but the other models are also in a this...

A trio of Trios from Laboratory series, Japan models.

Greetings, Tibi! I was tempted to purchase at some point the Sansui AU-Alpha 607NRA or the improved Sansui AU-Alpha 607NRA II (this has an extra transformer in the front for the preamp?), but bought something else instead. Now if I want to buy a less expensive Sansui I will focus on AU-607 Mos...

As far as I know, not only Sansui used MOSFETs in some of their integrated or power amplifiers. For example, Accuphase started to used them after their first models P-300/P-300S (these had BJTs). P-260, P-400 power amplifiers had Hitachi MOSFETs (see the picture below with my Accuphase P-260)...

Rottapha, are these the C-1 and B-2 the ones in the youtube videos?

What a beautiful picture!

Greetings, Pete! No need to replace any V-FETs, just that I would be much more comfortable with some spare V-FETs at hand in case something unfortunate will occur...

Congratulations for this long and tedious process, but with happy ending. Hope you enjoy your B-3 for long long time. One of the best sounding amplifiers in my opinion. I also found another B-3 locally which does not come out of protection, but not having your repair skills, I am reluctant to...

Hello, clinic-audio! I guess is in my nature to get more information, not that I do not trust what rottalpha said in the previous post. Moreover, now that you have certified that these cannot be replacements for 2SK76/2SJ26 based on your testing I will not search for these anymore (I found a...

Do you have any explanation as to why is a NO, maybe a datasheet of these transistors? I cannot find info regarding these VFETs from YAMAHA. Thanks!

I have stumbled upon this schematics of an organ from YAMAHA, and it is shown the V-FETs 2SK98/2SJ38 in the power supply. Moreover, one could observe that this was made for the Japanese market with 2SK98/2SJ38, while for the export model they used 2SK76/2SJ26 V-FETs. Hence, my question: are...

Broesel02, I guess this is where all the best from Kenwood/Trio goes, your collection. Congratulations for these beautiful masterpieces! PS.: I believe the best are the L-09Ms.
