Firstly, I must apologies for not being active on this thread for a while, I was thankful for some Hercules users trying to help me on this thread. This is not fair to listen to the story from one side. I must tell people what was happening from my side too. Then you can make your fair judgment.
Since this message has been there for quite long time, my reputation inevitably be damaged, I have no choice to disclose some emails to prove myself. I must emphasis that the reason for the overall damaging of that Hercules because user put glue or epoxy on the PCB to stick that Hercules board onto the turntable. I am not sure the glue is from new user or the user sold it to him. But the glue is quite new, looks like newly added. The fact is RD11s does not have standoff clips for Hercules board like LP12. But glue is not a good idea. As you know, some glue is possibly conductive when being exposed to high voltage, nothing to do with Hercules quality. As some user mentioned, it has been selling for more than 5 years, the complaints is rare.
The story begins :
I received an email from youngdand on 15 Feb 2012
I was hoping ou ma be able t help with a problem i am having with a hercules board aqquired from a respected member of this site.
The board is new, and unused. I have attached it to my aristone RD11s. The board powers up, and the switch lights up and changes speed no problem, however the motor doesn't spin, even with a little persuation. My Motors model number is 9904 111 31302.
Do you have an idea what could be causing this problem?
When I ask him to send me the photo of that board, that Hercules board was recognized 5 years old. I can identify from the components being used.
Because it is working but no power to the motor, I ask user to check the output voltage to the motor, actually, I am providing a free consulting service to him as usual.
youngdand replied to me that no voltage was being measured at output to motor.
My email to him
In that case, it is really hard to tell what is wrong with your Hercules board.
Unless you send it to me.
You can send to address below:
I will check the problem, I won't charge you more than USD50 including freight charge sending it back to you by speed post.
I wish it is acceptable to you.
reply from youngdand
Thanks that would be great. could you also make up a longer switch cable for me too? to fit an ariston rd11s, i believe you have made a few of these for other members. this would save me the bother. let me know how much this would be.
I will send the board over next week by airsure so should be with you by friday.
Once again thanks for your help.
Man, 32 quid including speed Post which cost me 15 quid and a free longer switch cable including modification to him because his application was RD11s.
Your board is fixed. The extension cable is done as well.
If you send the payment 32 quid to my PayPal account as below.
I can send it back to you by speed post after received the PayPal notification about the payment.
Is it a bargain?? I mainly try to help him to resurrect that Hercules board.
My email telling him what was wrong with his board on 2March2012.
Thanks for your payment.
I found there were trace of glue stick on the board, I have to clean most of them. In additional, one driving transistor is dead, replaced a new one.
I will ship it out in 1-2 days.
After sending back the Hercules back to him, he replied to me
The board arrived back. Worked fine for 24 hours. When i came to listen to some music this evening. no power. I have since found the fuse to have blown. One of the blue sincera 10d151k blue varistors apeaers to have melted off at the legs and detached from the board. I found this laying in the plinth of the turntable, and there was a faint smell of burning. The board is fitted exactly as instructed. it is mounted using nylon screws bonded to the crossbrace.
After reviewed the message from user about the Varistor melt off, I believe there were possibly still some trace of glue stick on that board was not removable or user put new glue again to stick that Hercules board onto his turntable. , that trace of glue may caused that Varistor damaged and dropped out when high voltage being conducted for 24 hours. This is good sign, it means the Hercules Varistor protection circuit is working fine.
Youngdand worte ,
Appalling. What is most serious, is that if a component on the board had not fallen out due to the excessive heat build up, is that it would have caught fire and burnt down my house.
This is over exaggerated, How does it catch fire???? if so, that Varistor will not be CE approved????? Or it should not be used in any electrical application.
In fact, I offered his a very good price of Mose, so he can send back his bad Hercules board. I will fix it for him free and installed that inside Mose , so he don’t need to fix that Hercules board by glue again.
After he received my offer,
No i cannot afford anywhere like that.
What i will do is pass this matter to my insurance company to look into. I can show that i paid for repair, and that it was not repaired. furthermore, if the component had not fallen out, then it could have burnt my house down. the turntable is stock, and wired according to uk law, so they can test the board to see if they can find fault and take it up with you directly.
My last mail to him
I have no comment until your insurance contact me, Sorry sir.
I try to resolve that issue with him friendly, but he want to settle this case by law.
I truly believe he will send that case to his lawyer, so I have nothing to do until his insurance contact me.
I didn’t know he try to bad mouth me on the forum instead.
