Kaya lang, won't get to hear it until Sunday. Just got it on way to airport so it's sitting at home while I'm on a trip. Aaargh.

Went to Sir Andrew Sevilla's shop today and went home with this:

Now I know what I have been missing. It gave life to my speakers. Listening to music has never been the same.

Andrew Jones Pioneer SP-52FS. Brought with me the speakers when I auditioned. At first I thought it would be hard to drive but amazingly the tube amp breathed life into it. Got the speakers last December so hindi pa masyado na break-in. The harmonics was so so good. Heard notes from familiar music I have not heard before. Even Sir Andrew was surprised. Rated at 18wpc which is enough for my small living room. Credit goes to you guys here in pdvd for introducing me to Sir Andrew.

Just got to hear it. Sweet!

Not enough time to really it down and get transported to another dimension but I can see I'll get there.

But now I know what Ricky is telling me about the ills of using your home theater room as a listening room. Almost wanted to tear down my sound absorption panels and bass traps. Will have to figure something out.

Next project would be my FR speakers. Drivers still to arrive end of month so will probably use whatever free time to build the cabinet...and enjoy the music, of course.

He-he. Not now. Not yet optimal. Still have to find time to tune the room and build the speakers.

Did we get the same tube amp? Mine is the Sonatina 5 PP EL84.

No. I did not look at the model of mine. But I have only 4 tubes, you have 7. In the middle of the chassis between pairs of tubes, there is a bias knob and dial.

Not sure what the sound quality and/or power difference are.

tony · « **Reply #139 on:** Feb 06, 2017 at 10:27 AM »

^most likely you got a single ended amp....just right for your fostex speaker....

sealander's is most likely an st35 clone, this is to me the best sounding
amp from AMX.....my speakers are 90db's....ymmv....

Nice looking amp, congrats!

OT: I have a nice AMX Pre-amp that developed a hum when I plugeed the rca in my amp while it was powered , my tech and I can't figure out where it is coming from (we've replaced suspected caps and tubes to no avail). Can you PM me Sir Andrew Sevilla's email address or phone number?
I am hoping he can provide me a schematic of the unit. Maybe Sir Tony here can also give his inputs. Thanks in advance.

are the volume pots at zero when that happened?

If I heard Mang Andrew right he said it was a Push pull EL84.

This happened to my amp when I connected the sub via the sub pre out. The rca cable were running on top of the speaker cables. So I rearrange the cables and the humming was gone.

you set up....

Yes my speakers are 87db. Bought my speakers last December so hindi pa masyado na break-in. Well for my ears it came alive so to speak. Better harmonics. High on the mids and very good bass specially when a subwoofer is in use. I heard notes from familiar music I've never heard before. Based on the reviews of the Andrew Jones SF-52FS most were saying that it lacked the needed bass. But lo and behold the bass was good enough for me. At first I was doubful that it could easily drive my speakers but My friend who accompanied me when I auditioned it and even Mang Andrew was surprised at the good harmonics and bass. I paired it with my circa 1999 Mordaunt Short two way floorstanders which is 90db and it sounded good too. I never knew what I was missing until now. Music never sounded so good.

Maybe cable rearrangement lang or try changing RCAs.

Hi Mang Tony, I believe it was not. It's case of over excitement, the AMX was my first tube. LOL
I just sent Andrew an email, I only had the amp for like 15 minutes (it was hand carried by my parents here in Canada) and have been collecting dust since then.
I can tell everyone that is a nice sounding pre-amp hence I hate just to throw it away.

Hi Sunset, sorry no, I am positive one of the component was toast, there is a potted item that I am asking Andrew if he can sell me a piece or two. We have replaced the filter caps in the power supply and all tubes to no avail. My tech also checked for wrong polarity and there was none.
I do not mean to hijack the thread but thanks all for input, highly appreciated! I'll start a new thread for updates.

I am more of an SS guy BUT tubes can put that magic in vocals. I am assuming majority here are enthusiast so by all means I recommend people to consider tubes in their collection. I always like the hybrid setup. Tube pre and SS amp.
