Good afternoon, everyone.

I’m currently looking for a good output transformer for an amplifier project and would appreciate some expert advice.

Specifically, I’d like to know:

• What key specifications or features should I pay attention to when choosing an output transformer in the budget/mid-range sector?

• Which manufacturers offer the best value for money in this price range?

• Are there any Chinese brands worth considering that perform well without breaking the bank?

Did the ultimate 2a3 deluxe amp with the ISO FC-30 transformer ever get built? Did anybody build this amp? The transformer shoot-out showed such good performance from the FC-30 that it makes me curious how such an amp would sound. I’m thinking about building one but I’d love to hear what someone else has to say of the sound produced by this ultimate build. I’m referring to a version with the silver wires, Horizon or EML tubes, RCA drivers, and maybe the alternate rectifier tube. If anyone knows anything concerning the performance of the FC-30 output transformers I’d like to hear what you have to say.

Stephe, I know you’re busy with the listening room and other projects but if you have any other suggestions for substitutions or tweaks from the standard Skunkie Designs 2a3 to the top shelf deluxe 2a3 I would love to get your thoughts. No rush,…

hi, everybody! please, I have a question: which fuse should I use on the SE KT88 kegger/blueglow amplifier in europe, on 230 volts grid? thank you in advance for any indication

Dear Stephe and Group,

I am so glad to have found this group!

Stephe's x7 review convinced me about getting one as my first try to returning to the tube world after 45 years (since I built a tube amp). However I have two questions that you may be able to answer given your huge and invaluable experience. I apologize for asking something that is obviously so subjective but I was hopping the measurable (objective) lessons you have learned may be able to generate a couple of answers :

1. If you had to pick a pre-amp for the X7, what would be some recommendations? Or, a link that discusses this. The dishonest full of garbage jungle that web has become is very unpleasant for me.

2. Have you heard any other amp that has made you happier than the X7?

With appreciation and respect,

Hi S

This is how a Quad S5 should look inside.

So glad you are feeling better.

Have a great Expona

Regards

A12

Finally got round to 2nd group of updates on A12.

Went with Rubycon Caps ( inc PC Boards ones ) and the Mundorf Oil Ali for couplers and Vishal Resistors ( all 3W )

Settled on 580k for shadenfrude link.

In all honesty I am shocked how a handful of Resistors and Capacitors can make such a DRAMATIC DIFFERENCE, it now sounds truly amazing.

Currently listening to John Martyn - Solid Air WOW.

To add to above, I got the A10 on special at £340, spent £80 on parts - so now have a fabulous sounding tube amp ( my first in 60 years ) for £420, quite ridiculous really.

Listening to it now, really does sound good.

Way back in the 80s had really top end gear - Krell, Spectral, AR, Vandersteen, Kiseki, et al.

Hi

Finally got round to doing Skunkie mods on my A10 ( now A12 ).

All I need to say is OMG the difference is unbelievable, improved in every aspect especially the BASS !!

Found the 860 ohm to bright so changed that to 680 ohm, might drop down a bit more as still just a tiny bit bright.

Went with TAD rectifier and JJ output tubes, still using as suppled PSvane EL34, must have got a good pair as image is rock solid.

Have JJ E34L and Mundorf caps on order, looking forward to them.

Hello all

I recently found Skunkies Chanel, she’s brilliant, very impressive advice.

Prompted me to get my 1st ever Tube Amp - Reisong A10 ( will wire as per A12 ) starting the mods tomorrow, while I’m at it is it worth changing the power supply Caps on PCB ? Mine are crappy looking Brown ones branded Nippon ?

Also not clear on the bypass caps ( currently little Orange ones ) what to change them for ?

Been in this “ Hobby “ for 60 years and spent far too much money over the years on many “ high end brands “ thought I was happy with my system but now bloody Skunkie has started me off again !!!!!

Let you know the outcome 🤞🏻🤞🏻🤞🏻🤞🏻.
