This unit was listed online for free, so me and a mate picked it up.

Unit does not turn on, and I can't find any information on it whatsoever.

I would be very happy if some could share their information about this anchor.

Hello and welcome.

Interesting to note that use of at least a couple of "Radiospares" components. These were generally supplied to repairmen and laboratories etc. so to me, this implies that Tiger Radio was a small-time operation, building only a small number of units. The 3-digit serial number tends to confirm this.

One of the reasons it wont work is that the large GEC labeled valve (second picture down) is down to air, hence why the top has gone white.

Looks like a quality piece of kit, and looks to be in great condition.

Indeed it looks like great quality, and feels so also.
Only thing is that there is some chassis sag, from the awfully heavy components. I carried this up some stairs myself, and it's certainly not some poorly made equipment.

I believe this is a transmitter, hence the TR prefix.

Tiger also made the Tiger TR200 transmitter.

Hi,

The Tiger Radio Company produced transmitters in the late 1950s. Until recently, I owned a TR200/HF but have now sold it as it was taking up a lot of space. I was unable to find any info on any of the TR series other than a set of operating instructions that someone had kindly put into a Word document. You are welcome to a copy of that document and also an article I wrote for "Signal" magazine about Tiger Radio.

There is quite a lot of similarity between the various Tiger transmitters, although the valve-lineup changed quite a bit. I had a TR-60B here for repair that was donated to a local museum and that was a cut-down version of the TR-100. Your "find" looks to be in good condition.

Regards,

I think that's a TT21, probably the PA stage or driver stage. The modulator looks to be a pair of KT-88s or 66s, worth a few bob to audiophiles.

Roger, what was the intended use of transmitters like this?

Well the bandswitch and tuning are marked with the "Pre-WARC" standard amateur Bands (and nothing else) so it's presumably intended to be used by Radio Amateurs. There's a "Fone/CW"switch on the Power Supply/Modulator so it was capable of both voice (AM double sideband) and morse transmission.

Hi,

Here's an advert for the TR-100, dated around 1960.

Hi Nick,

As Hugh says, ham radio on the original 80 to 10 metre bands, see the advert I've uploaded. AM and CW only, so really only of use on the vintage nets, although the CW performance is probably OK if you accept a little drift in frequency.
