I have no service manual for this radio.
Contact if you need yours.

Here is a quick summary of my HE-80 repairing;

Power Supply Filter Capacitor

--- Unbelievably the filter cap was okay.

Recapping in the audio stage

--- Some capacitors including 6AQ8-6AQ5 coupling showed leakage;
audio gain and response recovered.

Adding NFB

--- This was not necessary but for an experiment I added
NFB to the audio power amplifier. Audio gain reduced but
frequency response became far better.

IFT alignment

--- It was found that the IFTs were incorrectly aligned to the
secondary peak; properly aligning the IFTs to 455kHz regained the
sensitivity and selectivity. I think previous owner failed
the realignment.

Recapping the detectors

--- Capacitors in AM detector and product detector showed
severe leakage; recapping eliminated the audio distortion.

Coil Pack realignment

--- Sensitivity became better.

Q Multi Coil alignment

--- Q multi became operational.

Product detector mod

--- This was an attempt to improve the SSB detection; not
so much improvement observed. Need to work more.

The work is still incomplete. I plan to come back later
to work on this receiver again.

Great web site... I'm currently restoring a Lafayette HE-80 receiver and was wondering if you had an english version of the notes you posted when you did your restoration of the receiver? Also if you have a parts list for the radio?

Best regards,

Your radio restoration page is very nice. Thank you for posting the schematic for the Allied A-2515A. It allowed me to easily find the bad mechanical filter and restore mine. Now if I could find a service manual for my Icom DV-21 digital VFO!

Hello Paul;

Thank you for visiting NoobowSystems. I think complete replica glass scale for HE-30 (9R-59) is on the market. Please search the Net, I believe you can find one.

Hello Dan;

I am just starting to restore a Lafayette HE-30 Receiver.

I had one in the 1960's when I was a teenager but foolishly traded it in the early 1980's for a partially-working Galazy V ham transceiver.

I bought the HE-30 recently and found it was not in as good a condition as the guy selling it had said so ... I have some work to do.

Do you know of any sources for the dial markings ? The HE-30 I have has some damage on the right side of its dial and I wonder if anyone has a high-quality JPEG image of the HE-30 dial ?

Best Regards;

Thanks for the article on the SBE SB34.
I have one as well that needs restoration. Unfortunately it is not in its original box (metalwork) for some unknown reason the previous owner has transplanted into a new case. Your article has inspired me to make a start on the restoration.

Thank you for your restoration stories, specifications, and background on equipment made in Japan and rebranded for resale elsewhere. There *is* a special enjoyment in making "forgotten" equipment work again, and in developing understanding circuit and techniques used at particular price levels in an era.

As for me, I am interested in the Trio JR-500 amateur-band receiver, sold as the Allied A-2516 receiver in the states. At base I need its schematic, but I am also interested in learning of its relative popularity in Japan, any variants you know of, and whether or not a matching transmitter may have been available. (The receiver has a VFO-output jack and an octal socket that would have allowed some integration with a transmitter.) I am aware of the Allied A-2517 transciever (Trio TS-510?) but its IF/frequency scheme was different.

Thank you, and have fun,

David Newkirk
