Community Admin wrf 2,348 Posted December 19, 2019 Community Admin Share Posted December 19, 2019 Picked up an amp the other day. Sounds glorious on the Spatial Audio M-3 Turbos. Anybody recognize it? Also does a great job as a space heater. 3 3 Link to comment Share on other sites More sharing options...

Dadvw 2,594 Posted December 19, 2019 Share Posted December 19, 2019 Nice looking amp WRF! Yes, I am of the opinion of running my tube amplifier in the Fall/Winter and Solid State amps in the spring/Summer.....grin 1 1 1 Link to comment Share on other sites More sharing options...
oldtexasdog 2,108 Posted December 19, 2019 Share Posted December 19, 2019 Hows the sound compare between the two? 2 Link to comment Share on other sites More sharing options...

My system has undergone considerable change in the past few months. Speakers, preamp, and amp. The only constant has been the Transporter and the Sunfire sub. Both amps deserve a careful listening session before I come to any conclusions. Informal listening reveals considerable difference between the two, but more time is needed. I'll post a serious comparison in a few weeks. I posted this thread because the BAT has such an overwhelming physical presence, particularly when warmed up. The pictures show this, but not nearly to the degree of actually being in the same room with this beast. 3 1 Link to comment Share on other sites More sharing options...

4krow 3,233 Posted December 19, 2019 Share Posted December 19, 2019 Both devices might bee seen as hearing aids. 2 Link to comment Share on other sites More sharing options...
oldtexasdog 2,108 Posted December 19, 2019 Share Posted December 19, 2019 There should be considerable sound difference as the BAT is an SE styled amp and the Carver is not. I have an interesting experience and story with Bob and SE amps😉 2 Link to comment Share on other sites More sharing options...
Balok 1,299 Posted December 19, 2019 Share Posted December 19, 2019 Nice looking amp Wayne. I will be interested to read your review of the sound and the comparison to the Carver amp. I think the BAT is a push pull as well, no? 2 Link to comment Share on other sites More sharing options...
oldtexasdog 2,108 Posted December 19, 2019 Share Posted December 19, 2019 (edited) I believe so as I think they use the term "Series Balanced Amplifier" as I understand it is when two devices are in series between the power supply rails, but the input drive goes only to one of the devices, the bottom one of the pair; hence the (seemingly contradictory) Single-Ended description. The output is taken from the cathode of the top (not directly driven) device, which acts part way between a constant current source and a cathode follower but receiving some drive from the plate (anode) circuit of the bottom device. The drive to each tube therefore might not be equal, but the circuit tends to keep the current through the bottom device somewhat constant throughout the signal, increasing the power gain and reducing distortion compared with a true single-tube single-ended output stage. That is one of the ways they get the extra power as most SE amps are only 3 to 10 watts output. Kinda a hybrid approach.

Hey, for the $8,500 MSRP at least you get rivet nuts for the cover and lots of unpopulated parts locations on the PCBs !! What is with the tape on the caps ? 1 Link to comment Share on other sites More sharing options...

What is with the tape on the caps ? The 8 caps in the middle are a bit tall and can contact the bottom cover. They all have clear plastic insulators on them, but those 8 get an extra rubber pad (not tape). 2 Link to comment Share on other sites More sharing options...
