H…presumably the Hammarlund HC10 has gone (?) …mentioned in the 110 advert but not on site. Is that corrosion under the paint on the 110 front panel? Has the front panel been redone ? My regards
Do you have a power supply for the Yaesu ft200, dosn’t have to be in working order or other parts for the tranceiver.
Decent hosting for $10 a year or VPS for six bucks a month.
I have some transmitting tubes, would you be interested? They are 3×813, 2x CV2131. Am also interested in ATLAS tranceivers 210X, 215X, 350XL etc. any thing going?
Power Supply repair: Hybrid Radio
I am repairing an older hybrid radio from Korea … a Bando Technic 5. It blows fuses and a local amateur and I have found that one of the two HV electrolytics is a short circuit. The Bando uses two 47uF 450 volt electros in series with equilization resistors (470k) and RF bypasses (.01). I expect to replace all of these components. Modern capacitors (pcb type) are readily available … but they are tiny when compared with the chassis-mount originals. Are they going to be up to the job?? My guess is that the size of this component has been reduced by a factor of eight times! Has any reader replaced these components with modern ones?? You can reply direct to my email.

I remember radio house went there to buy transistor for Phillip’s electronics kit like Morrie like old valve radio have several Drake’s yasau ftdx400 401 560 made 20m metre ssb transceiver using a swan circuit and filter Vk2mu amateur 40 years I used 6cm5 finals
Its Maurie vk2dcd I have got stuff from you before..I am building a 40 mx valve cw transmitter….Looking for 50-100pf capacitors for driver tank…I used some Jackson type in my 20 mx home brew but I noticed some caps dislodged the vanes.These were a modern type not the wartime type . Have you got any good quality variable caps in the 50-100 pf…Also need to make up high wattage dropping resistors.. TWO 20K 10 WATTS IN SERIES and also any more 6146b valves…I planned to use 807 type but the 6146 would be better..Thanks for any help …Maurie
