Jolida Fx10

I think it is worth giving the Jolida a listen. I suspect the Dynaco would go louder and clearer if working properly but it might be a non issue depending on your lsitening habits. The Jolida surprised me in that regard for its size and cost when I heard it.

Definitely audition them with your speakers. Whether it works for you may also depend on the size of the room. Ten watts isn't a lot but my FX10 has more than enough power in an 11x11' office with a pair of fairly inefficient single-driver speakers. I continue to be amazed at how satisfying the sound is and I've had no problems with the FX10 listening to it several hours a day.

If you're new to tubes the FX10 is a good introduction. The auto-bias feature means you don't have to deal with that for awhile. Some tube amps that aren't auto-bias make it easy to set the bias manually but some are a pain in the ass to deal with.

Another advantage is that upgrades to the EL84 and 12ax7 tubes are relatively inexpensive and the amp does respond well to an upgrade from the stock EH tubes.

I recently sold my Jolida FX10 here on the A'gon. I recommend them highly. I used them in a 14x16 home office with stellar results. Never a problem and to get best results one should use high efficiency speakers (mine were generally Tekton 4.5s and Tekton Lore at times). The other thing is change out the stock Electro Harmonix tubes. I had great success with NOS Russian 7189s, Ei EL84s, TAD EL84s. For the 12ax7 I used NOS Telefunkens, Ei, Mullards as well as a Tubestore Northern Electric NOS with good results. In my room I often had a wall-to-wall stage that was nicely layered, good tone, love the EL 84s, fast and punchy, good enough detail, the little thing was just musical and went as loud as I could tolerate. The bass on the Lore was very good. Tight and lively. This amp plays way above its price point, great 2nd system or first if doing a desktop or just starting out with tubes. Really fun little guy.

I agree with Mikirob that you can have a great time with swapping tubes in the FX10 and that it's possible to make an improvement in the sound of the stock tubes.

If you're not comfortable with navigating the world of NOS tubes by yourself there are some excellent dealers like Jim McShane and others who can give great advice and provide you with tubes that are tested and matched.

Another alternative is to go for some of the best new production tubes like the Gold Lion EL84s and 12ax7s. Buying them from a reputable dealer is recommended there, as well.

While looking for some information about the Jolida FX-10, my google search brought me to this forum and as it turns out, Mikirob was the person that I bought the FX-10 from .

After 5+ years of continuous use, 40-50 hours per week, the amp finally developed a problem. It was at this moment that Jolida really shined. I called them up and spoke with one of their engineers that designs and builds the equipment. After a few minutes of troubleshooting, he had me mail it in for repair. While it was in for repair, i also had them perform a small upgrade (naked Z-foil resistors i believe).

Needless to say, i couldn't be happier with the amp and the people at Jolida. They really love the craft and their shows enthusiasm really shows.  I have bought other things from them and will continue to do so.
