Usher R1.5 should I buy?
Sorry I have no idea about the V1 and V2. I send the circuit diagram to you, Usher 2.5, same for 1.5 just less rail volts and output transistors. Should anyone else want it on Audiogon can you contact [email protected] and he will pass it on. Cheers George |
Thanks George got you mail. Thanks very much indeed. Heard the amp extensively today and I can vouch that this amp will blow amps costing $6000 straight outta water. People looking for power amps should really check this Amp first before blowing money on Big Brands which are unnecessarily expensive for other reasons than the main reason ... The Sound. I’m getting the R1.5 with a ss preamp later but a good preowned Shindo Auriges now . |
So glad I found this thread. I have 2 Usher 1.5's and run (ran) them in mono to a pair of Usher Tower XL's. One of my amps became noisy (right channel) and was shipped back to USHER for a replacement. Still waiting.... What I had learned was that Usher was setting the bias higher as it was discussed somewhere that the sounded even better at higher bias, and they already sound amazing. What a great amp and a beast. In mono it's stupid good. But I don't know how to set bias :( So I guess I'll "probe" around, find a pot, and adjust till my hand starts burning? Thanks! |

Seriously, please get a tech to do it, as you need to put dmm meter probes on the emitter resistors, and that is a hairy place to be, as it’s very confined. Cheers George |
