antee period, DYNACO will replace any non-stand-

ard parts at net prices. Many of the components are

standard items which can be purchased from most

electronic supply stores.

If transformers are returned for factory repair or

replacement, they should be removed from the equip-

ment without cutting leads short. If leads are cut

rather than unsoldered so that they are unusable, the

transformer guarantee is void.

In the event the assembled kit does not function

properly or breaks down after use, DYNACO will

service the kit for a fee of $5.00 plus the cost of parts

which have been damaged or are past guarantee. This

service facility is not available for kits which are in-

completely wired or which have been wired with other

than rosin core solder, or in which changes have been

made without factory authorization. In addition, NO

PARTS WILL BE REPLACED NOR WILL ANY

SERVICE BE RENDERED FOR KITS WHERE

THE GUARANTEE POST CARD HAS NOT

BEEN RETURNED. THE SERIAL NUMBER

ON THIS INSTRUCTION BOOK MUST BE

MENTIONED IN CORRESPONDENCE, PARTS

RETURN, OR KITS RETURNED FOR FACTO-

RY SERVICE. It is the factory prerogative to limit

the service facility to one year from date of purchase.

When shipping a unit for service, a note must be

attached specifying symptoms, the name and address

of the sender, and the serial number of the unit. The

amplifier should be securely packed with stuffing in-

side the cover to prevent the tubes from coming out

of their sockets in shipment. It should be placed in a

rugged carton and surrounded with plenty of shock

absorbing packing material. The original carton is

not suitable for shipping an assembled amplifier.

Shipping should be by Railway Express, prepaid;

repaired kits will be returned by Railway Express

collect for shipping and service charges unless these

are prepaid. Parcel post is not a safe method of ship-

ment for assembled units.

Dyna Co. assumes no responsibility or liability for

damages or injuries sustained in assembly or opera-

tion of the DYNAKIT.
