About upgrade service LTPW01(P)->LTPW02(P):
We have been testing and modifying the LTPW01(P) to further improve its sound quality.
Finally, we have developed and are now selling the external DC power supply LTPW02, which improves the sound quality of Cybershaft's OCXO clock products.
This upgrade service allows you to greatly improve the sound quality by changing the LTPW01(P) circuit, adding filter parts, and changing the output voltage to 15V.
In a blind comparison test conducted by Cybershaft staff, when used with OP15 products, they were able to identify upgraded LTPW02 products with 100% probability.
Please note that depending on your usage environment, you may not always be able to see the improvement effect.
How to apply and proceed with the upgrade:
You must send your LTPW01(P) safely packaged to our new address.
You can choose any shipping method you prefer, such as EMS, USPS, FedEx, DHL, etc.
You will only need to ship the main unit of LTPW01(P); there is no need to send AC or DC cables, nor the clock unit itself.
You will be responsible for the cost of shipping LTPW01(P) to Cybershaft.
When shipping, please indicate on the customs declaration that it is a shipment for repair of LTPW01(P) and include the Serial number (S/N: xxxxx).
To prevent double taxation in Japan, you must list the price of the item as US$ 50.00.
As a thank you, we will only charge $1.00 for the upgrade cost.
You will also need to cover the cost for us to send the upgraded LTPW02 back to you.
You can see an estimate of the shipping costs you will incur when we return your item to you after adding this service to your cart, registering your checkout information, and before payment on the next screen.
Of course, if you have any additional items you would like to purchase, you can add them to your cart and save on shipping costs.
In that case, please be aware that the price of the added item will be recorded on the customs declaration.
