So, the lineup would seem to be 6AN7, 6AD8 (or 6N8), 6BD7, 6V6GT, 5Y3GT. Definitely no 6AQ5.

I have nothing for Classic matching that line-up. Maybe that chassis has been stuffed with random valves (or has been modified).

GTC - Sorry my mistake I have now corrected the original post headline and had the model correctly identified by you and the other members a great appreciation for your support and knowledge valued thankyou all

I now are trying to sought out the heater voltage issue when the 6V6GT is plugged in shorting out the heater supply form 6.3vAC -0V across all valves as they are linked daisy chain

i have removed all valves except for the 3y5 rectifier and the 6V6GT
once removing the 6V6GT tube the supply comes back too normal

I will submit the pics to Brad to upload the chassis component wiring underneath and connections ptp
it may be wrong with the components and the connections
I received this unit someone had attempted to repair it previously as a unfinished project so its a unknown quantity too me as it was not working

I have tried 2x 6V6GT with the same issue
i have tested the filament integrity on a valve tester they pass as good
strangely the quality test shows no reading on the valve tester so my valve tester may be in question but that's another story to address

kind regards

.Wayne: since this is not an HMV model, please edit your original post's title and replace HMV with Classic.

NOTE: I have now corrected subject title and body to reflect Classic TG-4430 model

On another Note; can you assist or anyone else on the forum can chip in helping with a Shorted heater issue when the 6V6GT is plugged in
I have tried 2 x 6V6GT valves and they both still short out the 6.3vac supply
so I believe it must be a issue with the wiring on the 6V6GT socket and not the valves
i have tested this theory with all valves plugged in
I have even tried with just the rectifier 3y5 valve & the 6V6gt plugged in
when I unplug the 6v6tg valve the 6.3vac returns too normal .
can you please review the attached pictures that Brad will upload and asses the connections
your help and knowledge and the input from everyone on the forum regarding this technical issue is greatly appreciated

Kind regards
Wayne

Photos uploaded to Post 18.

Photos 2 and 3 are blurry. There's been changes between the photos as the components around the 6V6 have been altered.

On the 3rd photo I can see at least 8 wax caps that need replacing.

There's also some disconnected wires near the power transformer.

The 6V6 heater pins don't seem to be connected.

In the first photo, it looks like a few wires were cut. The heater (pin 2), the grid (pin 5), and that shielded wire that's touching pin 1.

There's also a pair of wax caps there which I hadn't noticed before. One of them is a nasty UCC which might be leaking into the grid and MUST be replaced. The other one is connected to B+ on pin 4.

In the 3rd photo, there's a new grid resistor, and although it's quite blurry, there's a new cathode electro. Can't tell if the heater has been rejoined.
