Sound thinking in my opinion. Primary 15H, DC resistance 189ohm. Its a 6sl7 grounded cathode - cathode follower capacitor coupled to the 2A3. Ads on/off / Custom Title / More PMs / More album space / Advanced printing & mass image saving Page 1 of 6 1 23 > Last »

RESULTS It give a good power and high sonic performances. The power supply is from a mainframe computer for the filiment and plate voltages. For the price I think it's an outstanding product and with the Hashimoto OPT it's really a joy to listen to.Best regards from Switzerland!Robert S" "I installed the 2A3FFX with Sylvania 5U4GB, Pure dual mono design, each channel's own output, choke, power transformers and tube rectified power supply stage on to the same chassis - Total 6 Transformers.DUO Feedback Technology , exclusive and other

You will never go back, I'm sure of it, everything else sounds a bit bleached and distorted. I may have one made for me, perhaps by Min of Tube Audio Lab, or I may try to pick up a used one. Like the time I saw Rory Block at the Ark from about ten feet away, as if I were invading her space or something. I was sad to see it leave – I don’t know when another component of this caliber might grace my room.

Like the time I saw Rory Block at the Ark from about ten feet away, as if I were invading her space or something. Keep it simple. Limited. http://forums.stevehoffman.tv/threads/is-the-45-the-best-power-tube-ever-made.143985/ I mean the bass has that satisfying weight to it that I've been missing.

You might try the same thing in your preamp and amp. I would be much better prepared to celebrate the 45s with some pics of your amps! but this is no longer a 300B amp. I've use mine in a direct reactance type amp I built (a variation on the Monkey or free lunch circuit) that is direct coupled: no capacitors in the signal path.

and not a monoblock because it use only half of the tube sections. see it here Well, the driver can drive the 300B grids 30 volts (!) positive, with no crossover glitch as it passes from Class A1 to Class A2. 45 Tube Amp Home - Contact Us - Advertise - Rules - diyAudio Store - Sponsors - Archive - Privacy Statement - Terms of Service - Top - Opt-out policy vBulletin Optimisation provided by 300b Vs 2a3 DaleH, Mar 26, 2008 #25 (You must log in or sign up to reply here.)

The presentation is dark, being centered on the lower midrange with a full, sumptuous bass.

If so, why?

Limited edition.Your choice of 12AX7 or 6H30 as driversPower output : 2A3 - min 4W max output power ; 45 - 2W before distortionThe 12AX7 version is hand made in our Made to Orders Only. There are some people whom favor a couple of other tubes over the 45 but overall it's hard to beat. A problem is, that available B+ for the drivers in that 2A3 amp is a bit on the low side for 6SL7 anyway. 6SL7 sounds best with about 200V at plate,

The 1812 by the DSO was another revelation, I got more emotionally involved with the music than ever before. The Altec's are 60's vintage green 416a 15" woofers and 802d compression drivers on 811b horns. However I was not sure about direct–coupled input/driver stage in there, and lately my doubts were confirmed: driver stage gave a lot distortion, and I have changed it for timely–tested SRPP Thinking back in my mind I could never tell what it really sounded like in there though; the "Academy Roll-Off" was in place so there was nothing over 8k on a

That's the challenge. Never heard a really low power system because no one I know has a speaker that can be driven by a 45 or 2A3. dividebytube, Mar 24, 2008 #12 Mike in OR Through Middle-earth...onto Heart of The Sunrise Location: Portland, Oregon Is the 45 the best power tube ever made? My next project will keep all the PSU components- all the AC and all the single-path far away from one another. 3.

I'm certain Shigeki Yamamoto would concur 100%. philefreakDetailsDiscussionsPostsThis discussion416 posts01-09-2003 4:00pmEditDeleteI'm a dealer, so beware! A. At a typical 8 watts, a 300B is only going to be 3 or 4 db higher than the typical 3.5 watts of a 2A3.

The 416's sounded light in the low bass with my SE845 with negative feedback, too much dampening factor for them. hvbias, Mar 24, 2008 #21 morinix Forum Resident Location: Sylmar (the land of olives and quakes), California Chad Etchison said: ↑ You wouldn't happen to have a stray issue lying about High quality Z11 Lamination import from Japan Designed for 2A3 or 45 Could be use for Self or Fixed Bais 250-0-250 150mA 0-CT-5V 3A, 0-6.3V 2A, 0-CT-2.5V 3A, 0-CT-2.5V 3A, Primary Of course due to low parts count, everything that goes in one of these amps is critical, tweakers take note: any part change is very noticeable.

Chad Etchison, Mar 24, 2008 #19 edisonphonoworks New Member Location: La Moille, Illinois USA I have a 301-A Line Stage pre amp that I built. They are 95db speakers, and I think the 2A3 amp will run my other system with 100db Altec 604s better. For the money the James is tough to beat and performs at the level (with great bass response) of the aforementioned iron. But I love my 45s even better!Much depends on the amp design that the tubes are in, but the 300B tends to be known to have plenty of bottom end and

I am looking at eventually buying a nice 300b amp. The driver tube is a 5842/417A. They weight close to 30 lbs without any transformers.Rectified and voiced by Mullard GZ32/ EML 274B (5U4/5V4 can be substitute, 5AR4/GZ34 not recommended on NOS/Old 2A3 and 45)Goodies - Cardas RCA
