Step By Step Assembly - Ten-Tec 1253 Assembly And Instruction Manual

Step-by-Step Receiver Kit Assembly
You will build the receiver in seven phases, testing the
completed audio circuit (Q4 and U1) before doing the detector
and tuning sections. The reason for this approach is that we
want to make very sure that any whistles and beeps you hear
from the receiver are real signals and not a malfunction of the
amplifier section. Once you experience the amplifier section
working properly, you can build the tuning/detector section with
confidence and test basic receiver operation on one band before
setting up the bandswitching system. Only after testing all
functions will it be time to do final wiring and cabinet assembly.
Model 1253 Receiver Kit Assembly Phases:
Phase 1: Audio Amplifier Stages (Q4 and U1)
Phase 2: DC Voltage Control and Regulation
Phase 3: Regenerative Detector and Varactor Tuning
Phase 4: Basic Receiver Operation Test
Phase 5: Electronic Bandswitch Board
Phase 6: Bandswitching components and wiring
Phase 7: Final wiring and cabinet assembly
We urge you to install all parts in the order specified in these
step by step directions. However, some builders may find the
following common questions and our answers helpful:
Q. I've built numerous kits. why can't I just install all parts as
listed and try out the finished radio when I'm done?
T-KITs, the 1253 receiver indeed will work as specified if all parts are
installed correctly. Our directions are intended to be as helpful as possible
to beginners; please also see the final Q&A!
Q. Can I do this work in any other order than detailed in this
A. You can build the Bandswitch Board (Phase 5)
manual?
anytime including right now. You can prepare the Main Tuning
Knob anytime. You can mount the battery holders to the battery
shelf anytime. otherwise, we think you'll find the sequence of
this manual to make good sense.
Q. Must I complete a single step such as installing one resistor
before starting the next one?
inserting several parts as one operation, soldering all points and
trimming all wires and then checking off all of them at once in
the blocks provided. Just remember that taking shortcuts can
cause mistakes in any endeavor.
