Default Japanese OPTs

Dear All,

I am struggling to choose a no compromise OPT for my Tubelab SE 300B.

The candidates are:

Tango FC-30-3.5S
Hasimoto H 30-3.5S
Hasimoto H 20-3.5S
James 6123H

I tried a pair of James and they are not bad, so I am tempted to try something different. Do you have any experience with this iron ?

Thanks,

Davide

Just to add to your confusion you can add to your list the Softone RW-20.
I have a pair and like them but that of course does not mean a lot to you but they are on the cheaper side in cost but do not sound cheap.

You want to add Tamura to the list and propably scratch James - they make nice transformers, but it's not the same ballpark as Hashimoto or Tamura.

I am in the same situation and finding it hard to decide.

Tango and Hashimoto are great no compromise options, but man, pricey. Also along those lines might be Silk.
They have a good "shootout" on the silk site SACThailand, if you are interested and they perform well compared to the Tango and Hashimoto and much better (in my interpretation) than the James.
Price would be good, too, except shipping adds another $100.

Cost-wise I am leaning to the James. Although maybe not quite in league with the others, there have been numerous other good impressions on this site. Which means a lot to me anyway.

I have also been looking at the following two on e-bay. Look interesting. Price may be ok. Good reviews or at least stats.
I would really like any opinions on them too.

BTW- don't worry about me should you decide one of them is to your liking. I don't call dibs on them by any means.

Being in the US, you should also consider the O'netics from Bud in WA. There is a range from cheap to expensive and are price/performance competitive with the Japanese OPTs.

Good thought. i have been interested in the O'Netics, but Bud hasn't answered a PM from last week. I will try again.

I really respect his input into this forum, although a lot of it is WAY over my head. I wouldn't mind considering his OPTs.

Make sure you send him an email. A PM thru the board can easily be missed (why i have mine turned off)

I did not include Tamura, as their prices, even in Japan, are unbelivable !!!

So I remain with Tango or Hasimoto. By the way they do not have big fantasy in giving names to transformers :-)

Tango FC-30-3.5S
Hasimoto H 30-3.5S

Let's try another way: do you think is worth going for the 30 W models or the 20 W is more than enought ? From a 300 B I don't think more than 20 W are coming out, but maybe there is some other reason to choose a bigger OPT.

Best Regards,

Davide

Dave,
For the noobs here on the forum, how does one get in touch with O'netics/"Bud from WA"? An alternative (especially local, I assume you're referring to Wa. state) to the run-of-the-mill OPT's would be fantastic.
Thanks,
Bill
