Anybody else who can help? I need correct AWG and ohm for coils Many thx in advance

Excellent Job, Could you please help me with the correct AWG for the coils. Im working on an upgrade of my RF-83 as well. Great!

Blue one, otherwise it will not Glue😃🙂😄

Thanks, I think I will indeed stop; it already sound quite good. I will look at the resistor/Caps position again. What's the problem if caps overlaps resistor? Just curious

Perdon me! I may be speaking in lay man's language. Yes, indeed COILS

Now gradually to the next stage: What do I stand to gain changing the Core/Inductions? Any personal experience/s?

Thx MicroMara. I made little mistake during my ordering; ordered 2x "1ohm resistors) instead of 4😄 Now have to wait for the other 2 to arrive. what do u think of my component combination? Update will follow soon

I would like to try anything that will bring more wao experience. Having said that I could hear quite clean music coming out.................

Its done! At least I finished one speaker and able to compare: Pleasant to listen to not harsh compared to the original one (I did put 2/10ohm Transistor in parallel). I used Jantzen Superes transistors all round. photos say it all. How long does it take for the Clarity "CSA" caps to burn in? I played it the night long and could hear it getting much better. However I expected a bit more than Im experiencing now. Thus any suggestion for improvement is very much welcome: State now: 2x Clarity CSA (5/12uf) in serie HF 1 Clarity CSA 18uf in parallel with 16uf (Jantzen Cross Cap)

Which components (brand) did u use?? Apart from SONICAP which is obvious🤔

In case someone thinks GONE WITH THE WIND!😄 I've been busy with source of Income lately! Now to push project to finalisation below are my choices: I surely want to buy my items here in EU I want to stick more to JANTZEN and Clarity (CSA) products I understood Clarity (CSA) are one of the least critical and due to size thus I want to use them for my HF (5uf & 12uf), only that the 5uf have to now be 5.1uf due to availability, which I understood, the 0.1uf will not make much difference Where necessary I intend to Flip the PCB to make this possible for The Capacitors in Parallel 16uf and 18uf, I will use JANTZEN CROSS CAP However, The series on HF (5uf and 12uf) are Non-Polarised (NP) can this work. sorry this is a little bit beyond my knowledge. I read somewhere that it doesnt matter as long as you then make sure +/- are facing correct direction As regards resistor I will use (Jantzen Superes) 2x 1ohm 1x 2ohm and 1x 10ohm to achieve the "Deang" prescribed solution for Horn. - I would have loved to use Mundorf Mresist for the 2ohm/10ohm combi but due to non availability of 2ohms (which I find strange) and I do not want to use single 1.8 which gives higher ohms than suggested 1.66 I will leave the coils and Core for now I need your response PLEASE In the first place as regards item 6 NON POLARISED (NP) CAPS ANY OTHER SUGGESTION IS ALSO VERY MUCH WELCOME. Thanks in Advance

I appreciate very much the explanations. I talked to a friend today who is Electrical engineer (not into Audio though) who explained nicely to me the reason why Deang's repeated advice to use 2ohms and 10ohms in parallel is of better advantage to using single 1.8ohms in an attempt to reduce the ohms. Not only will it reduce the ohms to 1.66 [10*2/ (10+2)]. But the reliability is much more robust (pls allow me to use a lay language here) and will handle what it has to handle with more easy and accuracy. Makes complete sense. Now, I intend to use 2 highly rated resistors (mondurf mresist classic, 2 and 10 ohms) in parallel there. First reason is for the size/less space they occupy and 2nd reason is that if there is more reliability to attain I dont want to miss it, especially not for the little extra cost. Do I make sense? @Deang, Since SOLEN is not available here locally but Mondurf, Jantzen etc any other suggestion of COMPATIBLE Caps for the Low Frequency (LF) board? I will surely use Jantzen Crosscap on High frequency as suggested, That is settled! I will not touch the Coils but I surely want to also change the 5uf and 12uf (reason is that if there is more reliability to attain I dont want to miss it, especially not for the little extra cost), Any suggestion pls on most compatible for this area. I saw that Jantzen Crosscap is NP like the original caps

Does anybody have clue/experience in this combination:? Jantzen Superior Z which is like 8x more expensive than Jantzen Crosscap to replace the 2x 18uf caps (one on LF the other on HF) 12uf & 5uf on LF to use Jantzen Crosscap? but there is challenges with getting exact 5uf, I can only get 5.1uf of the Jantzen Crosscap

Yes, To make it alround, I understand using 1.8 resistor instead 2ohm will reduce sharpness somewhat. Totally open to all advice from someone who owns 9 (waoo). I am all ears................

@Deang Thanks for the swift response. Do you really mean that the added performance gotten from using Jantzen Superior which is like 8x more expensive than Jantzen Crosscap is not worth it, so I may therefore go with JANTZEN CROSSCAP? I actually meant to use Jantzen Superior Z for the 18uf but for the 12uf & 5uf, is it then ok to use Jantzen Crosscap? but there is challenges with getting exact 5uf, I can only get 5.1uf of the Jantzen Crosscap Anybody else with experience using this combination?
