Default Problem with new L3-3 please help!

Good evening to all

I recently bought the L3-3 off ebay username: sunnygirl505
Item number: 300918041965


I chose to buy from this seller because it indicates that it is new, calibrated and fully functional condition!


After reaching the tester the first picture was beautiful outside box was flawless! In potentiometers were some oxidation but did not bother. The cards look new and the manual! Additional tubes not look new and some had black marks! I opened the fuse holder which selects and the supply voltage and found that fuse had placed three wires! I put it back in place.


I put the cable to the mains and switch on to heat as described in instructions. The tester after a bit faded .. I opened the safety and found that it had blown. I replaced the fuse reopened the switch and after a few seconds again burned.

I contacted the seller and told me that tester was double tested before shipping and this must be some problem in transit!


Externally as I said was excellent with no sign! I turned to see and internally. I found that there was no sign to indicate that something is shorted.


I contacted the seller again and after inform that nothing happened on the transfer request one of three
1. To refund me 250 euro for repair
2. To send it back and send me another one in full working condition + the cost I would pay to return
3. To send it back and refund me all the money I paid + the cost I would pay to return


He replied that because the high cost 150-200 euros returned, better to have it repaired but can not give me so much because the repair costs 20-30 dollars in her country and reaches 80-90 dollars in other countries.


I contact a professional technician who proceeded to diagnosis. Found many small problems (burned resistors) but the main thing is that the primary of the transformer is shorted! The cost would be at least 250 euro!!


Again I contacted the seller and informed diagnosis and demand
1. To refund me 250 euro for repair
2. I send it back and refund me all the money I paid + the cost I would pay to return


She told me to send it back and she will make a refund in accordance with the rules of ebay!
I find it unfair that happens, she sent me something that does not match the description and she wants me to pay with the cost of shipping.


Can someone help me please; What do you suggest me?


Thanks
Alexander

Default Yes Paypal should get you a complete refund.

Provided you used Paypal for payment. Also save the email exchange about the item. I got a complete refund on a non-working preamp. Don't leave any feedback till this is resolved.... The down side of Ebay........

What voltage you have in your power outlet? L3-3 can be configured for 127V, and if you connect it to 220V, sure there will be burn out

There are many L1-3 and L3-3 passed through my hands, but I never encountered problems with power transformer.

I can do this. Ebay and Paypal will tell me send it back and seller will give you the money you paid, but not the carrier who I will pay, or not;
I think is unfair to pay 150-200 euros from the moment I received something that is not as described!

I have 230V. manual say 220+-22. This fuse does not leave you to make mistakes....
the tester came to me with three wires as a fuse isn't this suspicious?
primary shows 2,1 ohm only.Is possible the main is good and something else is wrong?

I'm currently have several L3-3 testers. Primary is 2.8 Ohm on one and 3.4 Ohm on another. By R(DC) your seem to be OK, but it doesn't mean there are no primary shorts.

Please note - fuse holder acts as input voltage switcher !!!

So you need to take real fuse, and insert fuse holder with 220V pointing to the bottom if you have 220V power line.

Its quite possible one of the electrolytes or diodes in power supply gone south, and simply created short on secondary. Again, broken power transformer is quite unusual for L3-3, Rewinding/repair is possible, but due to enormous number of windings it will be quite time consuming and expensive.

PS. I think seller checked one L3-3, and sold the rest of the stock as is. You bough it from a surplus e-bay seller, not professional electronic specialist, so all surprises are possible.

Depending upon your location, it may be worth to take anything you can from ebay seller, and try to repair it.

There are several occasions which will lead to the burnout of resistors for sure.

Please check short user manual on my blog:
L1-3/L3-3 Vacuum Tube/Valve Tester User Manual | MacGuru HQ

Anyway, disconnect wires from power transformer leading to high voltage stabilizers, or at least take away tubes L1, L2, L8, L16 from them. Then insert new fuse and try again. If fuse stays alive, power transformer probably is OK.
