Post Subject: No-amplification timePosted by Romy the Cat on: 4/5/2011

I do not want go for emergency ULF amps and to pay more than $50 for it, in fact all plate amps shall cost $50. I will probably end up getting another B2 amp, identical to the one that blew up with the identical changes. I just felt that this no-amplification times a good opportunity to see where I stay on the powerful SS amps. The powerful SS amps all sound very different in bass and it might be a good time to try something different, to get some reference of what is possible out there. I even thought to get my extra pair of monster LF transformers, attach it to a full-range Milq that I have and to try it on my bass towers. Sure with 20W it will not go very far but at low volume it might be worth to try. I have some kind of another 60W tube PP amp that a local audio guy left in my home but it will not be LF DEST and most likely it naturally roll of at 20Hz.

The problem with testing of the tube amps and ULF is that loading become very important and with wrong loading all bets are off. To set a tube amps for a proper symmetrical clipping at maximum power into the given load is not so hard but it is a processes itself – I would go over it is it was 100W tube DSET that I would keep but I do not weans to go over it with a temporary amp. I might borrow some amps from local dealers but I do not have the local dealers with whom I have established relations. I use to have but they are gone to different fields. To borrow from dealers I do not know the amps that I have no intention to buy - I do not feel comfortable to do it.

I might rent some pro audio SS powerful amps. It might cost some little money but it will be no stench of hi-fi retailer. Again, how nice would be to have a local technician: I have full-assemble Zarathustra II amp that Dima built for me and all part for very expensive PS. For half day a technician would put everything together, I would like the person to work in my lab and use my test equipment – I will juts pay for his time. Would it be so great – to write a check, to get home and to have a fully working Zarathustra II, over 200W in class A is sitting in my home. I need to do it sometimes myself but I would REALLY would like to outsource all those tasks. It might be a good dig for right person…
